Infrared observations of the 2006 outburst of the recurrent nova RS Ophiuchi: the early phase
A. Evans, T. Kerr, Bin Yang +20
We present infrared spectroscopy of the recurrent nova RS Ophiuchi, obtained 11.81, 20.75 and 55.71 days following its 2006 eruption. The spectra are dominated by hydrogen recombin…
The Spitzer IRS view of V4334 Sgr (Sakurai's Object)
A. Evans, V. H. Tyne, J. Th. van Loon +11
We present an observation of the very late thermal pulse object V4334 Sgr (Sakurai's Object) with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope. The emission from…
Infrared observations of V838 Mon
M. T. Rushton, T. R. Geballe, A. Evans +3
We describe the results of fitting simple spherically symmetric models to the first overtone CO and AlO A-X (2-0) bands in V838 Mon. We find that the temperature and column of both…
Variability of V838 Mon Before Its Outburst
S. Kimeswenger, S. P. S. Eyres
Archival observations of the progenitor of V838 Mon were re-calibrated as well as multiple images from the 2MASS and the DENIS near infrared surveys. Both - the better calibrated v…
An asymmetric shock wave in the 2006 outburst of the recurrent nova RS Ophiuchi
T. J. O'Brien, M. F. Bode, R. W. Porcas +6
Nova outbursts take place in binary star systems comprising a white dwarf and either a low-mass Sun-like star or, as in the case of the recurrent nova RS Ophiuchi, a red giant. Alt…
The Real-Time Evolution of Sakurai's Star (V4334 Sgr) and other (V)LTP Objects
P. A. M. van Hoof, M. Bryce, A. Evans +10
We report on the progress of our on-going campaign to monitor the evolution of the VLTP objects V4334 Sgr and V605 Aql, as well as the suspected (V)LTP object CK Vul. V4334 Sgr doe…
