... 1. How might you tell the difference between a Type Ia and a Type II supernova? (I.e. what observations might you make in order to decide if a given supernova was of a given type? Think about this either for a supernova which we’ve just observed exploding, as well as for a historical supernova where ...

... 5: 0.1 and 100 M⊙ . The minimum mass is set by the mass at which it is possible to have H fusion. For M < 0.1 M⊙ , the core is not hot enough for H fusion, and thus the object is not a star (it would be a super-Jupiter or “brown dwarf”). The physics of the upper mass limit is not known. We simply do ...

A light bending effect due to the sun’s gravitational field, should, as theoretically predicted by General Relativity, take place at the Gaussian sphere, 2R, yielding 1/2 of 1.75 arcsec, at the Gaussian sphere, 3R, yielding 1/3 of 1.75 arcsec. This should be noticeable for nR using modern technical ...
