Gaia DR2 White Dwarfs (NEW ADDON)

23516 "sdB" is a valid spectral class in SE. It is equivalent of "B VI". Ups, you are totally right. It wouldn't make sense if SE didn't have that sorry. And yes spectral classification is quite "an art" at some point. There are a lot of schemes when you go in detail a...

Gaia DR2 White Dwarfs (NEW ADDON)

For the 120 White Dwarf binaries I ask for a community addon here. You can take the data from the attached file. The spectral classes are similar to those used in SE but there might be some differences. For example, a DAB2.4+M is a binary with a DAB White Dwarf (SE allows for the specific kind of DA...

Gaia DR2 White Dwarfs (NEW ADDON)

23504 But this is solitary white dwarfs? WD in binary systems, which was not resolved by GAIA, still lurking there. Exactly! Yes, I should have noted that. If there is a high \Delta m in a binary (like the case of Sirius), the high contrast would still hide the White Dwarf. We have reached complete...

Gaia DR2 White Dwarfs (NEW ADDON)

23397 I hope the catalog will be included in SE 0.990. Regarding this I talked previously with Vladimir and he think it is better to have this as an addon for the moment until we can integrate a significant amount of Gaia data in Space Engine. Why? Because in this way we avoid having unrealistic pr...

Gaia DR2 White Dwarfs (NEW ADDON)

Gaia's White Dwarf catalog Size: 73.221 White Dwarfs It has been a while since I said I would start working on Gaia's DR2 implementation in Space Engine (and I haven't show anything until now). A lot of decissions are been made and we are still probing how well behaved is the astrometry and the...

The Future of Humanity & Intelligent life in the universe

That's very interesting An'shur . I'm very skeptical with FTL travel been possible at all but expansion rates are an interesting topic in relation to all the speculative field of the Fermi paradox. I'm also very skeptical of extraterrestrial intelligence at all. I like the fact you thought about...

I even understood 10% of it, it was so well explained! Hahahahahaha :lol: I'm learning a lot right now while I make this so plase add me to the prehistoric group of people here. Ok so let me say that I have changed a lot of the previous post because I think I was falling into another missconception...

Solar System dynamics discussion thread

21371  I did try directly computing orbits with and without perturbation just to try to get some intuition for how the perturbation effect works.  For starters I assumed co-planar, circular orbits, and also that only Neptune perturbs Uranus and not vice versa (which probably matters very little). W...

Simulation Hypothesis Topic

22388 They would say that the astronomers methods are 'unfalsifiable'  from their viewpoint, simply because they do not understand them (having never studied physics, chemistry or astronomy in general). I have to agree with Watsisname here. I think the fact that something is important or not is not...

What exoplanet might reply us back?

A paper has been published that examines the Earth as an exoplanet from the context of transit detection methods from other stellar systems. So this is a little off-topic but I prefer to write this here since a new thread would be unnecessary in this case. The paper is called " Transit Visibil...
