V838 Mon: an L supergiant?
- A. Evans, T. Geballe, V. Tyne
- Physics
- 11 August 2003
We present a 0.8‐2.5 µm spectrum of the peculiar variable V838 Mon, obtained on 2002 October 29. We see one of the coolest stars ‐ certainly the coolest supergiant ‐ ever observed, with deep water…
A radiation transfer model for the Milky Way: I. Radiation fields and application to high-energy astrophysics
- C. Popescu, R. Yang, Dublin Institute for Advanced Studies
- Physics
- 18 May 2017
We present a solution for the ultraviolet (UV) - submillimeter (submm) interstellar radiation fields (ISRFs) of the Milky Way, derived from modelling COBE, IRAS and Planck maps of the all-sky…
Discovery of multiple shells around V838 Monocerotis
- J. Loon, A. Evans, M. Rushton, B. Smalley
- Physics
- 7 July 2004
We report the discovery of multiple shells around the eruptive variable star V838 Mon. Two dust shells are seen in IRAS and MSX images, which themselves are situated in a shell of CO. This securely…

Circumstellar discs in the young σ Orionis cluster
- J. Oliveira, R. Jeffries, J. Loon, M. Rushton
- Physics, Geology
- 10 March 2006
We present new K- and L � -band imaging observations for members of the young (3‐5 Myr) σ Orionis cluster, obtained at the United Kingdom Infrared Telescope (UKIRT) with the UKIRT 1‐5 micron Imager…
Galaxy And Mass Assembly (GAMA): Gas Fueling of Spiral Galaxies in the Local Universe. I. The Effect of the Group Environment on Star Formation in Spiral Galaxies
- M. Grootes, R. Tuffs, M. Rushton
- Physics
- 21 December 2016
We quantify the effect of the galaxy group environment (for group masses of 1012.5–1014.0 Me) on the current star formation rate (SFR) of a pure, morphologically selected sample of disk-dominated…
Spectral evolution of V838 Monocerotis in the optical and near-infrared in early 2002
- M. Rushton, T. Geballe, S. Eyres
- Physics
- 11 July 2005
We report optical and near-infrared spectroscopy, and optical spectropolarimetry, of the peculiar variable V838 Mon during the multiple outburst phase in early 2002. The spectral evolution is…
The Early Infrared Temporal Development of Nova Delphini 2013 (V339 DEL) Observed with the Stratospheric Observatory for Infrared Astronomy (SOFIA) and from the Ground
- R. Gehrz, A. Evans, S. Starrfield
- Physics
- 16 October 2015
We present ground-based infrared photometry, JHK spectroscopy, and 5-28 micron SOFIA FORCAST spectroscopy documenting the early temporal development of Nova Delphini 2013 (V339 Del). We derive a…
STEREO/HI and optical observations of the classical nova V5583 Sagittarii
- D. Holdsworth, M. Rushton, M. Darnley
- Physics
- 18 December 2013
The classical nova V5583 Sgr (Nova Sagittarii 2009 No 3) has been observed during the rise phase and shortly after by NASA's STEREO/HI instruments, with later optical spectroscopy obtained with the…
The Spitzer Infrared Spectrometer view of V4334 Sgr (Sakurai's Object)
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 5‐ 38 μm is…
