None of our gas giants are anywhere near brown dwarf mass and that is probably why. If we had one it would have been studied intensity since centuries back. Brown dwarfs are not really large but they are massive. That would confuse astronomers when they effect orbits more then Jupiter do.

Yeah same here! They were ones I intentionally avoided when picking route options, along with black holes, white dwarves, and the other proto-stars. Aside from binary systems with close-proximity stars (there has to be a term for that), these were the most terrifying upon hyperspace exit. The primary reason being their occlusion zones were huge compared to the stellar body's diameter. So it was an immediate struggle to avoid damage and getting pulled from Supercruise. Unless I was explicitly exploring, I refused, lol.

@mikedrop4421 Год назад

See this is why I love this channel. Obviously as planets get bigger their mass increases but then at a certain point which is obviously the size of Jupiter it starts to go the other way for a while and the planet stays roughly the same size but the density increases until you end up with so much mass in one spot it collapses in on itself and becomes a star. In my head I just thought of brown stars as being ginormous planets. I never really thought about the fact that at a specific size they would increase in volume logarithmically to their mass and that point is around the size of Jupiter. Cool stuff sure

@joshuacherry9113 Год назад

It's actually probably closer to the mass of Saturn where this phenomenon starts. Notice that the difference between Saturn's and Jupiter's masses is rather larger than their difference in radius or volume. This implies that Jupiter is not supported purely by gas pressure, but also partly by electron degeneracy pressure. This is also part of the support of brown dwarfs, and is why they don't get larger as they increase in mass. In the case of white dwarfs, which are entirely supported by electron degeneracy pressure, as they get more massive they get smaller in radius, but brown dwarfs and large planets like Jupiter are also partly supported by gas pressure, and fusion in the case of actively-fusingnbrown dwarfs.

@GrandpasPlace Год назад

Heading back to the Orion-Spur from the Perseus Arm I've come across a lot of Class-L brown dwarfs, most of them are the primary star in the system with 3 to 7 small planets that are little more than balls of Ice. The only Class-Y I remember is one that was in a system orbiting a main sequence star at just over 4000Ls. It had a beautiful and wide set of rings around it, that one I took a picture of as it stood out. Either way, the coloring is always amazing and they tend to give the ships interior a pink hue.

@AlbinoJedi Год назад

I love that Jupiter being a "failed star" was brought up. haha. While I've never heard it put that way, it blew my mind when I found out Jupiter is pretty much made of the same thing as a star but just isn't massive enough to initiate fusion. Can you touch on the details here (or correct me if I'm wrong)? This info leads me to at least understand where the "failed star" argument comes from.

hey there mr lucid, your old videos on magnetic fields are really awesome and coming in handy right now, but I had one doubt... is there a way to visualize magnetic vector potential...i mean may be even the vector identity of : curl of curl of a vector field is equal to gradient of the fields divergence minus divergence of its gradient.... (we are having its applications in antenna theory and wireless communication...where its only a equation but i really wanted to understand this...) thank oyu for your awesome content through out the years...!!

@ScienceAsylum Год назад

I visualize the magnetic potential just like any other vector field (see this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LbJJFnf-NWM.html ). The problem is that potentials require a "gauge" to chosen. They're not unique.

@hamjudo Год назад

I have often pondered the related question of how to animate a 3D vector field in an intuitive way. The best way I've seen to animate a 2D vector field has been used to visualize wind patterns. Windspeed and direction are represented by flowing textures, the speed of the flow in the image is proportional to the windspeed. This is a start, they add other visual cues to make it work better. The textures contain stripes that are parallel to the wind direction. The wind speed modifies the colors used in the animation. I don't ever recall seeing a good visualization of a 3d vector field, so I am hoping someone answers your question.

@ScienceAsylum Год назад

@@hamjudo I've made a 3D vector field visualization before. They're just not very helpful. The amount of information conveyed is a bit too overwhelming. Taking a 2D cross-section retains the most important information in the visual. If you really want to keep the third dimension, your next best option is to use lines instead of arrows.

@jamesdriscoll_tmp1515 Год назад

Interesting stuff. When I think of stars, especially red dwarves, I think of flare ups. Since brown dwarves are not fusing, are they more stable? Do brown dwarves have "solar wind" at all? Could a brown dwarf orbit close to a binary partner and see heating like a hot jupiter? Would that heat be enough to push it into fusion?

@joshuacherry9113 Год назад

A brown dwarf, assuming a mass of 13 or more Jupiters, does perform fusion, specifically fusing deuterium into helium, which takes less energy than doing fusion using ordinary hydrogen. This releases a fair amount of energy, but not enough to let much of any actual light shine through the clouds. At lower masses, even the heat is so mild that methane can be found in their atmospheres, and in such a case (a Y dwarf) a planet would have to be orbiting inside the dwarf's clouds to get any meaningful heat from it. Just like with stars, as brown dwarfs get more massive, the fusion reactions intensify, and by the time you get to T dwarfs you might start getting sufficient he as t outside of the dwarf itself to heat the surface of a tidally-locked planet around it, but its orbit would be ridiculously close to the dwarf, such that you might be looking at a year measured in hours. Cram enough mass onto your brown dwarf (approximately 60-70 Jupiter masses) and it reaches sufficient internal heat and pressure to trigger the fusion of Lithium, and at this point you might get a limited solar wind out of it, and this brown dwarf might be able to have a planet around it which is tidally locked but just far enough away to be somewhat habitable, although it would still emit almost no visible light. To the extent that it does emit light, it might look something like a giant charcoal ember glowing faintly in the sky. Whether deuterium burning or lithium burning, these objects don't have sufficient mass to enable sustained fusion. They may fuse deuterium for a few tens of millions years, or lithium for a few million, but they exhaust their fuel relatively quickly, primarily because the elements they fuse are rather uncommon. Very high mass brown dwarfs can briefly reach core temperatures capable of true hydrogen fusion, but they can't sustain that for more than a few scant hundreds of thousands of years, as they lack sufficient mass to sustain the necessary pressure in the core. Eventually, the fusion stops, and they cool off over billions of years.

@@ScienceAsylum OK I don't know science, but could you do a video on the Universe expanding? and is it? My theory is that there is a speed of Gravity and everything is falling in all directions, stretching time and space. Like the apple :)

What is interesting is that brown dwarfs are unlikely to have any planets that developed life from photosynthesis....but they are stable enough to have a "habitable zone" that could harbor a terraformed planet where an ecosystem is brought there. They should not be ruled out as a possible destination for a future colony. A greater percentage of UV radiation would mean the planet would have to have an atmosphere at least as thick as earths....and the "year" would be much shorter with the "habitable zone" being much closer to the brown dwarf.

I feel like Brown Dwarfs are the "Pluto" of the stars. "Oh you are not big/round/hot/bright/fillinrandomdenominator enough so we don't find you worthy"

Has been confused about the brown dwarf class for a while already. Thank you for making this so much clearer for me!

I didn't even notice it until people started pointing it out in the comments.

5:00 I'll take that personally!

I always loved how most logically, brown dwarfs should be called "asteroids". But that name, shittly, was already taken. "Asteroids" should be called "planetoids".
