NOV 22 Colloquia
Who Are Your Neighbors and How Much Do They Weigh?
Dr. Todd Henry
Georgia State University
ABSTRACT
The sample of stellar neighbors within 10 parsecs of the
Sun will be explored. The RECONS (Research Consortium of
Nearby Stars, based at Georgia State) effort to discover new
nearby stars and to characterize this fundamental sample will
be discussed. Discoveries from an observing program in Chile
to reveal members of your neighborhood will be highlighted,
as well as recent results from HST that are used to map out
the mass-luminosity relation for your lightweight neighbors.
Empirical determinations of the luminosity and mass functions,
which have direct bearing on the total mass of the galactic
disk, will be presented.
