I have found plenty of needed catalogues in Aladin database, however with different types of data, according to mass-radius only or indirectly: temperature, luminosity - just to set the radius. I go shares with anyone interested in this subject, list of those catalogues below: Nearest stars...

Probably you're right, I suspected that too, that's why I asked. It would me more judicious to find stars by mass yet, I don't believe there is no such a catalogue! Anybody? Anyway, thanks for help. I'll keep seeking.

Thank You, your reply was very helpful. Would it be ok if I use Eddington relation: Luminosity-Mass (L~M3) to estimate mass of a star? There are 345 results for absolute magnitude and effective temperature filters. I think it should be enough for my diagram. Anyway, I can't find masses for...

Hello, I need to determine Mass-Radius relation for stars, as I prepare myslef to finish my study work. I know it's possible to evaluate it theoritically in the form - M~Rn, but I have to prove it using empirical, observational data. Making a M(R) relation diagram is indispensable so I have...

Hello everybody! ;) I've got problem with task below, I've got few days to solve it and I've got some troubles: On inclined plane with variable angle of inclination we set cylinder and ball on the same height above the ground. The friction factor for both objects comes to 0,1 - it's the...
