They are!
Electromagnetically and gravitationally and chemically they act like stars.
Gas giant simulations are often performed by stellar codes such as mesa. Stellar physics and stellar simulations with fusion turned off. Morphologically, they are stars. We should move on from the cold war brain’s fusion chauvinism.
They are fundamentally different objects than planets. They have their own planetary systems. They’re stars, just unlit.
Juno gravity results imply Jupiter’s core is dissolved hydrogen plasma sludge, also known as the dilute core model. Kronoseismology (using saturn’s rings as a seismograph; Cassini read it like a DVD) implies the same is likely true for Saturn due to the discovery of g-mode waves mixing with the f-mode signal detected by ring occultations.

Y dwarf stars are a mix of what was previously classified under those mass classifications.

Here they are on Wikipedia’s list of Y-class brown dwarves.
Jupiter and Saturn are in fact brown dwarves.
Stellar classes are OBAFGKMLTY, from most to least massive.

Jupiter and Saturn are brown dwarves, and fit many definitions of “star”.
They are both large enough to have developed a hydrogen plasma core furnace that dissolves the rock and ice that was once their core. They are more than just a hydrogen atmosphere, down to the core they’re a big ball of plasma undergoing all of the same physics as stellar tissue, except the pressure at the center isn’t enough to ignite fusion.
Uranus and Neptune, meanwhile, are likely too small for this, and maintain a fluid ice layer and rocky core beneath their hydrogen envelopes. There is not enough hydrogen for it to take over these worlds. Therefore, they are planets, not brown dwarf stars.
Jupiter and Saturn, however, have grown large enough for the hydrogen to have turned to plasma and dissolved and supplanted their cores with a plasma furnace.
The solar system has three stars. We are not too early to explore other star systems. We know of many planets around Jupiter and Saturn. The extraterrestrial planet with most earth-like atmosphere and surface geology that we know of is Titan, and it’s in our neighboring (sub) star system. Huygens and Juice and Europa Clipper and Dragonfly are humanity’s first missions to planets around other stars.

- Comment on Lord of the SCIENCE 2 months ago:
No, even without an atmosphere you have to contend with the diffraction-limited resolving power through an aperture (pupil), which is related to the diameter of the aperture and the wavelength of light.
A diffraction process is, mathematically, a fourier transform. A fundamental mathematical feature of a fourier transform is what’s known as the uncertainty principle.
Side note: you’ve probably heard of the special case of an uncertainty principle encountered in quantum mechanics frequently misattributed to the head of the Nazi nuclear program (Heisenberg), but this mathematical principle was actually well known for centuries beforehand, and the misattribution is mostly because of Nazi propaganda. We see it anywhere a fourier transform is used, from optics to orbital dynamics to quantum particles. This mathematical phenomenon is frequently miscited as quantum “weirdness” even though there’s nothing quantum (or all that weird) about it.
The pupil restricts the possible positions of incoming photons. A restriction in position increases the variance of momenta (for a photon, speed never changes, but the momentum vector can still change direction). A smaller pupil is more restrictive and causes the image to be blurrier as the incoming photons from each object you are trying to resolve. If you want to be able to resolve smaller angular sizes (small objects at large distances), you need a large aperture that reduces position restrictions on incoming photons and therefore diffraction-induced blurring due to momentum uncertainties.
Look up Airy diffraction for the special case of a circular aperture (e.g. a pupil or telescope).

I searched “gtx 1660 vs amd” and saw that your card is usually compared to the rx 590 from amd on speed tests, with similar results. Price is also similar.
One example that includes the prices I was comparing. I have used neither card. I’m not familiar with that website. Do your own research before making a purchase,

What motivated you to switch branches? Did it solve another issue? Why were you not on the latest branch yesterday, ie, why did you roll back originally? Does one driver work better for some games, and another driver works better for others?
Nvidia drivers are jank. I honestly haven’t touched them since 2017. I remember having to reboot and switch drivers to switch games I was playing with friends and finding the whole experience annoying as hell. I realized that Linus Torvalds was right, fuck nvidia, AMD is the way to go. Have not had to touch anything with my drivers since switching. All of my interactions with nvidia since have confirmed that they are not a company deserving of my patronage.
- Comment on Is linux actually gaming ready or is it just not for me? 2 months ago:
Please try versions 535 and 470.
See if either fixes your issues.
You need to reboot after switching. It’ll take you 30 mins max, even if neither works and you have to switch back.

There’s usually only like 5 tracks. “What’s recommended” is nouveau, which works but not for gaming. It’s recommended because it’s open source and can do most things that the proprietary nvidia drivers can do. Nvidia is really bad at maintaining their drivers, and different drivers work better for different cards.
Nvidia sucks. Switch to AMD and never have a problem again. Or spend an hour testing each of the proprietary options maintained in the debian repos, and most likely find that at least one of them works. Until an update to the drivers or kernel comes along, and breaks it again, so you have to play around with driver versions and kernel versions to find a combo that works. That’s less likely to happen if you stick with a debian-based distro vs a bleeding-edge distro like arch.
And buy AMD for your next machine to send a message to nvidia that their driver support sucks!
- Comment on Is linux actually gaming ready or is it just not for me? 2 months ago:
Each nvidia card works better or worse with different version releases of nvidia drivers. Older cards usually need smaller version numbers. Since you are running mint, all versions you need to test should be in the default repos. Try different drivers and see if you can find the right one for your card.
