Infrared 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...
