JOHN R. STAUFFER'S HOMEPAGE
Hello and welcome!
If you are looking for the Open Cluster database created by
Charles Prosser and myself, click
I am the "System Scientist" for the
SIRTF Science Center
(Space Infrared Telescope Facility) is the
last of the NASA "Great Observatories", and
is currently scheduled for launch in July 2002.
I am also a CoI for
IRAC camera - one of the three science instruments on SIRTF.
Finally, I am
Project Scientist for the Submillimeter Wavelength Astronomy
which is centered at the
Harvard-Smithsonian Center for Astrophysics.
When I have some spare time, my primary research interest is in various
aspects of the evolution of low mass stars, and in particular low mass
stars in young open clusters.
My long-continuing research interests are in the rotational velocity
evolution of low mass stars and in the search for brown dwarfs in open
clusters. I have also been involved in a large effort to obtain
ROSAT observations of most of the nearest open clusters. With my
collaborators Lee Hartmann and David Barrado, I have recently completed
papers which estimate the age of two of the most prominent "Beta Pic"
stars. Another recent paper used the Keck observatory LRIS spectrograph
to determine lithium abundances for brown dwarf candidates in the Pleiades,
and from the location of the "lithium depletion edge" derive an accurate
age for that cluster. Many of the brown dwarf candidates observed
for that program were selected from deep imaging surveys of the Pleiades
described in two other recent papers (one by Bouvier et al. and the
other by Stauffer et al.)
