Re: Supernova SN1987a

So IIP or not IIP - that is the question.

Is there a list somewhere of the characteristic light curves of each Supernova type?

By the way, thanks to you both for your answers so far.

APOD: The Mysterious Rings of Supernova 1987A (2002 Mar 31)

A couple of questions:

1. What type of supernova is/was SN1987a?
2. Do you know where there is a gallery of pictures showing the evolution of SN1987a from the time of detection to the near present day?

Comet Holmes: Orbital Parameters

Does anyone know if the orbital parameters of Comet Holmes have been calculated?

In particular, I would like to know if the velocity of the comet changed from before the explosion to after.

TIA
