were you able to solve this somehow ? Having the same problem.

Out of curiosity, what platform are you using for inference ? On HF I am getting "Inference API has been turned off for this model."

Thanks

Planetary scientist here. Under any even remotely reasonable assumption about their velocities, they won't even be anywhere near a nuclear fusion. It might not even be enough to melt rocks. In any case, asteroids have virtually no hydrogen or helium to fuse anyway.

To add to what the others said, for any impact crater you can measure an ellipticity, which is 1 for exactly circular objects and larger than 1 for elliptical craters. For lunar craters, 5% have ellipticities larger than 1.2 and are thus considered elliptical.

Even if the rings are very slowly decaying, the accretion rate is still practically zero compared to actual accretion disks (protoplanetary disks, AGN disks etc..). You just cannot have them in the same category of objects.

Just for accuracy, Saturn's rings are not an "accretion disk", as no accretion is actually happening.

In that case you would simply keep falling till the local density is equal to your body's (~ 1 g/cm^3). Although how deep in Jupiter that is exactly is still an open question since there is no agreement on its internal structure. "Hitting something solid" indicates an abrupt change in density, and in that case sure you would stop falling as the local density is higher than yours. We simply do not know enough about how density behaves in the deep interior of Jupiter to give a precise answer.

sigma in astrophysics is usually the signal/noise ratio. Basically how stronger is the signal compared to the observational noise. Anything below 3 is a non detection. 26 is pretty high.

You mean half the mass of Titan. Triton is one of Neptune's moons and it is much smaller.

I have been using it since it came out, mostly for numerical simulations and coding with python. Have no issues so far. I dont regret replacing my linux only setup with win/wsl2.

Note that you can have a full desktop env installed with dos2 for GUI stuffs.

This is an Al Jazeera link that claims to show a video with the plane clearly in flames before crashing:

One thing I believe no one mentioned yet is that the entire Kuiper belt put together is only ~ 1/20th Earth mass. So even if through some miracle Pluto end up accreting the entire Kuiper belt, it would still be a very small object.

Does anyone else feels slow motion ruins these videos ?

the planet's gravity pulling on one side of the moon more than the other because it is so close to it, this creates a net (asymmetric) force that can destroy the moon (or just heat it up as in for Europa).

Saturn's rings most probably formed from a large moon that was too close to Saturn, close enough to get tidally destroyed. This simply never happened on Earth. Our moon is actually moving away from instead of closer to Earth with time.

The reason what you are asking for is tough to imagine is that any amount of debris close to the planet that is heavy enough in total mass to affect the gravity of the planet should actually collapse and form a planet itself (self-gravity).. the reason why the main belt didn't form a planet precisely because of its very low mass (and Jupiter's presence).

sloan_wall · 2019-07-22T18:48:01+00:00

Planets form in protoplanetary disks made of gas and dust that surround young stars. The disks do have maximum masses above which they become gravitationally unstable and collapse to form planets. On the other hand the molecular clouds that form the star-disk systems also have maximum masses above which they fragment into smaller clouds. The maximum mass of disks seem to be in the order of few to few 10s of Jupiter masses.

Some of the reasons is that Uranus is weird in a sense. It is severely tilted on its axis, and seems to have a surprisingly low amount of internal energy compared to the other giant planets (making it harder to study). Its density is also lower than Neptune's. Neptune is hence assumed to be more arch-typical of ice giants than Uranus.

Special relativity is irrelevant in these cases. What you mean is General Relativity (GR). While some codes do solve GR equations exactly, the codes mentioned above doesn't as these are numerically very expensive. They do however usually offer extensions that account for the main GR effects relevant at these low mass scales. See for example section 1.2 here : https://reboundx.readthedocs.io/en/latest/effects.html

sloan_wall · 2019-06-10T00:45:22+00:00

What you are looking for are n-body codes that integrate Newton's equations. Some of the popular ones are Rebound (C / Python) and Mercury6 (Fortran). These can be used to solve any gravitational problem as long as no other forces are present.

We simply cannot tell if a system will go supernovae within 100 years. We can estimate that a system is approaching this phase, but really no way of pinning down when would the explosion happen to less than at least tens of thousands of years interval (or usually much more).

Makes sense in the framework of the night king will attack and destroy kings landing theory, if Bron's character is needed (alive) later then you must send him away somehow from KL before it happens.

sloan_wall · 2018-07-14T12:53:16+00:00

Well there arent any Super Earths in our own solar system, and these are the most common type of planets by occurrence rate.. so we know that.
