Cepheid distances from the SpectroPhoto-Interferometry of Pulsating Stars (SPIPS) - Application to the prototypes delta Cep and eta Aql
Antoine Merand, Pierre Kervella, Joanne Breitfelder +8
The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface bright- ness technique, is an elegant method to determine distances o…
Spectroscopy, MOST Photometry, and Interferometry of MWC 314: Is it an LBV or an interacting binary?
Noel D. Richardson, Anthony F. J. Moffat, Raphaël Maltais-Tariant +34
MWC 314 is a bright candidate luminous blue variable that resides in a fairly close binary system, with an orbital period of 60.7530.003 d. We observed MWC 314 with a combinat…
The Ages of A-Stars I: Interferometric Observations and Age Estimates for Stars in the Ursa Major Moving Group
Jeremy Jones, R. J. White, T. Boyajian +12
We have observed and spatially resolved a set of seven A-type stars in the nearby Ursa Major moving group with the Classic, CLIMB, and PAVO beam combiners on the CHARA Array. At le…
First Images of Cool Starspots on a Star Other than the Sun: Interferometric Imaging of Andromedae
J. R. Parks, R. J. White, F. Baron +14
Presented are the first interferometric images of cool starspots on the chromospherically active giant Andromedae. These images represent the first model-independent images of…
Interferometry of Aurigae: Characterization of the asymmetric eclipsing disk
Brian Kloppenborg, Robert Stencel, John D. Monnier +17
We report on a total of 106 nights of optical interferometric observations of the Aurigae system taken during the last 14 years by four beam combiners at three different interf…
Detecting the Companions and Ellipsoidal Variations of RS CVn Primaries: II. omicron Draconis, a Candidate for Recent Low-Mass Companion Ingestion
Rachael M. Roettenbacher, John D. Monnier, Francis C. Fekel +14
To measure the stellar and orbital properties of the metal-poor RS CVn binary o Draconis (o Dra), we directly detect the companion using interferometric observations obtained with…
Robust high-contrast companion detection from interferometric observations. The CANDID algorithm and an application to six binary Cepheids
A. Gallenne, A. Mérand, P. Kervella +15
Long-baseline interferometry is an important technique to spatially resolve binary or multiple systems in close orbits. By combining several telescopes together and spectrally disp…
Detecting the Companions and Ellipsoidal Variations of RS CVn Primaries: I. sigma Geminorum
Rachael M. Roettenbacher, John D. Monnier, Gregory W. Henry +17
To measure the properties of both components of the RS CVn binary sigma Geminorum (sigma Gem), we directly detect the faint companion, measure the orbit, obtain model-independent m…
Spectral and spatial imaging of the Be+sdO binary phi Persei
D. Mourard, J. D. Monnier, A. Meilland +25
The rapidly rotating Be star phi Persei was spun up by mass and angular momentum transfer from a now stripped-down, hot subdwarf companion. Here we present the first high angular r…
