[Chennaipy] Minutes of May meetup: corrections in the astro talk.

[Manjari Bagchi]

Hi all,

Thanks for inviting me to give a talk in your meet-up, and also thanks to
Vivek for a summary of an astrophysics talk!
However, I would like to clarify a few issues (kept with "?") with Vivek's
summary:

 Neutron stars are not 10 times heavier than the sun. They are 1 to 2 times
of the solar mass. They are formed when stars 10 times or more die (a
significant amount of mass is lost during the death or the supernova
explosion).

Yes, galpy did all the calculations but the plotting window was called by
matplotlib.

 Not me, I am basically a theoretician. Interested people might think to
contact relevant persons in NCRA.

 Yes, but the team involves theoreticians also.

 Thanks and regards,
Manjari
