Oh, hello. I didn't expect to see you here. I'm Dan A. Nusdeo, research astronomer at Georgia State University as part of the RECONS team. My current research is a robust study of the multiplicity rate of K dwarfs in the solar neighborhood, primarily utilizing the infamous speckle cameras, DSSI, NESSI, Alopeke, and Zorro, to resolve companions at sub-arcsecond separations. This, in combination with a comprehensive literature survey and current/upcoming Gaia data releases, should provide us with a precise view of the multiplicity fraction for our small orange friends.

Aside from working with RECONS to establish a comprehensive database of our local stellar neighborhood, I am also interested in globular clusters and the information they provide us regarding the history of our galaxy. I'm a Connecticut native and a lover of the northeastern outdoors, which I miss dearly. I also miss good pizza, a rarity here in the south. In my free time I'm a musician, a gamer, and a hockey player. Feel free to leave a comment below. Go Bruins and Pats!

RECONS: Research Consortium on Nearby Stars

Summary a la Todd Henry: RECONS formed in 1994 with the intent of understanding the nature of the Sun's nearest stellar neighbors, both individually and as a population. The projects described below are all associated with the overall RECONS effort. Our goals are to discover "missing" members of the sample of stars within 10 25 50 parsecs (163.1 light years) and to characterize all stars within that distance limit. New members are found via astrometric, photometric, and spectroscopic techniques, or through companionship studies at small and large separations. Characterization includes photometry and spectroscopy at both optical and infrared wavelengths, as well as determinations of the luminosity function, mass function, and multiplicity fraction of the nearby stars.
