We have assembled new Spitzer Space Telescope IRAC observations of the mysterious binary star ϵ Aurigae, along with archival far-ultraviolet to mid-infrared data, to form an unprecedented spectral energy distribution (SED) spanning 3 orders of magnitude in wavelength from 0.1 μm to 100 μm. The observed SED can be reproduced using a three-component model consisting of a 2.2+0.9−0.8 M☉ F-type post-asymptotic giant branch star, and a 5.9 ± 0.8 M☉ B5±1 type main-sequence star that is surrounded by…

Infrared images of the transiting disk in the ε Aurigae system
TLDR
Interferometric images are reported that show the eclipsing body moving in front of the F star, an opaque disk that enshrouds a single B5V-type star in Epsilon Aurigae.
THE INVISIBLE MONSTER HAS TWO FACES: OBSERVATIONS OF ϵ AURIGAE WITH THE HERSCHEL SPACE OBSERVATORY
We present Herschel Space Observatory photometric observations of the unique, long-period eclipsing binary star ϵ Aurigae. Its extended spectral energy distribution is consistent with our previously
Large distance of ε Aurigae inferred from interstellar absorption and reddening
The long-period (P = 27.1 years) peculiar eclipsing binary e Aur, which has recently completed its two year-long primary eclipse, has perplexed astronomers for over a century. The eclipse arises from

XMM-NEWTON OBSERVATIONS OF THE ENIGMATIC LONG PERIOD ECLIPSING BINARY EPSILON AURIGÆ: CONSTRAINING THE PHYSICAL MODELS
We report on an XMM-Newton observation of the unusual, long period (F0 supergiant + cool disk companion) eclipsing binary star ϵ Aurigæ observed in X-rays prior to the onset of the 2009–2011 eclipse
Nova-like Cataclysmic Variables in the Infrared
Nova-like (NL) cataclysmic variables have persistently high mass transfer rates and prominent steady state accretion disks. We present an analysis of infrared observations of 12 NLs obtained from the
VVV-WIT-08: the giant star that blinked
We report the serendipitous discovery of a late-type giant star that exhibited a smooth, eclipse-like drop in flux to a depth of 97 per cent. Minimum flux occurred in 2012 April and the total event
Effects of dust on light-curves of ε Aurigae-type stars
Context. � Auriga is one of the most mysterious objects in the sky. Previous modeling of its light-curve assumed a dark, inclined, non-transparent or semi-transparent dusty disk with a central hole.

CO Delta-v = 2 absorption lines have been detected in the infrared eclipse spectrum of Epsilon Aur. These lines arise within a gas torus associated with the 'unseen' companion to the F Ia star. The

Recent observations of the eclipsing system of ɛ Aurigae converge to a conclusion that its secondary (‘invisible’) component constitutes a flat disc, some 40 AU across, which is semitransparent, of
