Identification of the TW Hya Association member 2M123539: a tertiary component of the HR 4796 system
Joel H. Kastner, B. Zuckerman, M. Bessell
The association of the late-type star 2MASS J12354893-3950245 (2M1235-39) with a bright X-ray source detected serendipitously by ROSAT and XMM-Newton, combined with its proximity t…
Spectrophotometric properties of pre-main sequence stars: the Epsilon Chamaeleontis cluster
A-Ran Lyo, Warrick A. Lawson, M. S. Bessell
We present a study of flux-calibrated low-resolution optical spectroscopy of ten stars belonging to eight systems in the ~ 5 Myr-old Epsilon Chamaeleontis (Eps Cha) pre-main-sequen…
M dwarfs: effective temperatures, radii and metallicities
L. Casagrande, C. Flynn, M. Bessell
We empirically determine effective temperatures and bolometric luminosities for a large sample of nearby M dwarfs, for which high accuracy optical and infrared photometry is availa…
Chemical similarities between Galactic bulge and local thick disk red giant stars
J. Melendez, M. Asplund, A. Alves-Brito +8
The evolution of the Milky Way bulge and its relationship with the other Galactic populations is still poorly understood. The bulge has been suggested to be either a merger-driven…
Gas and Dust Associated with the Strange, Isolated, Star BP Piscium
B. Zuckerman, C. Melis, Inseok Song +15
We have carried out a multiwavelength observational campaign demonstrating some of the remarkable properties of the infrared-bright variable star BP Psc. Surrounded by a compact du…
Discovery of new nearby L and late-M dwarfs at low Galactic latitude from the DENIS database
N. Phan-Bao, M. S. Bessell, E. L. Martin +9
We report new nearby L and late-M dwarfs (d_phot <= 30 pc) discovered in our search for nearby ultracool dwarfs (I-J >= 3.0, later than M8.0) at low Galactic latitude (|b| < 15 deg…
