Interferometric Studies of the extreme binary, Aurigae: Pre-eclipse Observations
We report new and archival K-band interferometric uniform disk diameters obtained with the Palomar Testbed Interferometer for the eclipsing binary star Aurigae, in advance of the start of its eclipse in 2009. The observations were intended to test whether low amplitude variations in the system are connected with the F supergiant star (primary), or with the intersystem material connecting the st...
متن کاملInfrared Studies of Epsilon Aurigae in Eclipse
We report here on a series of medium resolution spectro-photometric observations of the enigmatic long period eclipsing binary epsilon Aurigae, during its eclipse interval 20092011, using near-infrared spectra obtained with SpeX on IRTF, mid-infrared spectra obtained with BASS on AOES and IRTF, MIRSI on IRTF and MIRAC4 on MMT, along with mid-infrared photometry using MIRSI on IRTF and MIRAC4 on...
متن کاملInter-Eclipse Spectroscopic Snapshot of Epsilon Aurigae with HST
A single-epoch low resolution GHRS spectrum of the eclipsing binary Epsilon Aurigae was obtained while the secondary was orbiting towards eclipse by the primary. The spectrum as recorded between 1175—1461 Å is rich with emission and absorption lines which include stellar and interstellar components. The emission line profiles have the appearance of double-peaked emission with a stronger red com...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Multi-Site observations of SU Aurigae⋆
We present results from the 1996 MUSICOS (MUlti-SIte COntinuous Spectroscopy) campaign on the T Tauri star SU Aurigae. We find a 2.7-d periodicity in the He i (587.6 nm) line and somewhat longer, less well-pronounced periodicities in the Balmer lines and in Na D. Our observations support the suggestion that the wind and infall signatures are out of phase on SU Aur. We present Doppler images of ...
