The variable stellar wind of Rigel probed at high spatial and spectral resolution
O. Chesneau, A. Kaufer, O. Stahl +5
We present a spatially resolved, high-spectral resolution (R=12000) K-band temporal monitoring of Rigel using AMBER at the VLTI. Rigel was observed in the Bracket Gamma line and it…
Investigation of a transiting planet candidate in Trumpler 37: an astrophysical false positive eclipsing spectroscopic binary star
R. Errmann, G. Torres, T. O. B. Schmidt +50
We report our investigation of the first transiting planet candidate from the YETI project in the young (~4 Myr old) open cluster Trumpler 37. The transit-like signal detected in t…
The Berlin Exoplanet Search Telescope II. Catalog of Variable Stars. I. Characterization of Three Southern Target Fields
T. Fruth, J. Cabrera, R. Chini +11
A photometric survey of three Southern target fields with BEST II yielded the detection of 2,406 previously unknown variable stars and an additional 617 stars with suspected variab…
The Multiplicity of High-Mass Stars
R. Chini, A. Barr, L. S. Buda +5
We report about an ongoing photometric and spectroscopic monitoring survey of about 250 O- and 540 B-type stars in the southern Milky Way with the aim to determine the fraction of…
The eclipsing binary TY CrA revisited: What near-IR light curves tell us
M. Vanko, M. Ammler-von Eiff, T. Pribulla +3
New photometric observations of the hierarchical eclipsing TY CrA system were taken in the optical with VYSOS6 and in the near-IR with SOFI and REMIR. They are the first observatio…
A Possible Detection of Occultation by a Proto-planetary Clump in GM Cephei
The YETI Collaboration, W. P. Chen, S. C. -L. Hu +41
GM Cep in the young (~4 Myr) open cluster Trumpler 37 has been known to be an abrupt variable and to have a circumstellar disk with very active accretion. Our monitoring observatio…
