Twins Among the Low Mass Spectroscopic Binaries
M. Simon, R. C. Obbie
We report an analysis of twins of spectral types F or later in the 9th Catalog of Spectroscopic Binaries (SB9). Twins, the components of binaries with mass ratio within 2% of 1.0,…
Nearby young stars selected by proper motion. I. Four new members of the Beta Pictoris moving group from the Tycho-2 catalog
Sebastien Lepine, Michal Simon
We describe a procedure to identify stars from nearby moving groups and associations out of catalogs of stars with large proper motions. We show that from the mean motion vector of…
The Detection of Low Mass Companions in Hyades Cluster Spectroscopic Binary Stars
C. F. Bender, M. Simon
We have observed a large sample of spectroscopic binary stars in the Hyades Cluster, using high resolution infrared spectroscopy to detect low mass companions. We combine our doubl…
The Highly Eccentric Pre-Main Sequence Spectroscopic Binary RX J0529.3+1210
G. N. Mace, L. Prato, L. H. Wasserman +3
The young system RX J0529.3+1210 was initially identified as a single-lined spectroscopic binary. Using high-resolution infrared spectra, acquired with NIRSPEC on Keck II, we measu…
Periodic accretion from a circumbinary disk in the young binary UZ Tau E
Eric L. N. Jensen, Saurav Dhital, Keivan G. Stassun +6
Close pre-main-sequence binary stars are expected to clear central holes in their protoplanetary disks, but the extent to which material can flow from the circumbinary disk across…
Dynamical Mass Estimates for Incomplete Orbits: Young Multiple Stars in Taurus and Ophiuchus
G. H. Schaefer, M. Simon, T. L. Beck +2
We present recent measurements of the orbital motion in the binaries, DF Tau and ZZ Tau, and in the triples, Elias 12, T Tau, and V853 Oph. We observed these systems with the Fine…
