The eta Aquilae System: Radial Velocities and Astrometry in Search of eta Aql B
G. Fritz Benedict, Thomas G. Barnes, Nancy R. Evans +4
The classical Cepheid eta Aql was not included in past Leavitt Law work (Benedict et al. 2007) because of a presumed complicating orbit due to a known B9.8V companion. To determine…
Dissecting the Quadruple Binary Hyad vA 351 -- Masses for three M Dwarfs and a White Dwarf
G. Fritz Benedict, Otto G. Franz, Elliott P. Horch +8
We extend results first announced by Franz et al. (1998), that identified vA 351 = H346 in the Hyades as a multiple star system containing a white dwarf. With Hubble Space Telescop…
Testing Metal Poor Stellar Models and Isochrones with HST Parallaxes of Metal Poor Stars
B. Chaboyer, B. E. McArthur, E. O'Malley +7
Hubble Space Telescope (HST) fine guidance sensor observations were used to obtain parallaxes of eight metal-poor ([Fe/H] < -1.4) stars. The parallaxes of these stars determined by…
The Solar Neighborhood XXXVII: The Mass-Luminosity Relation for Main Sequence M Dwarfs
G. F. Benedict, T. J. Henry, O. G. Franz +8
We present a Mass-Luminosity Relation (MLR) for red dwarfs spanning a range of masses from 0.62 Msun to the end of the stellar main sequence at 0.08 Msun. The relation is based on…
Discovery of binarity, spectroscopic frequency analysis, and mode identification of the delta Sct star 4CVn
V. S. Schmid, N. Themeßl, M. Breger +12
More than 40 years of ground-based photometric observations of the delta Sct star 4CVn revealed 18 independent oscillation frequencies, including radial as well as non-radial p-mod…
HST Fine Guidance Sensor Parallaxes for Four Classical Novae
Thomas E. Harrison, Jillian Bornak, Barbara E. McArthur +1
We have used data obtained with the Fine Guidance Sensors on the Hubble Space Telescope to derive precise astrometric parallaxes for four classical novae: V603 Aql, DQ Her, GK Per,…
