Lifetime of OH masers at the tip of the asymptotic giant branch
D. Engels, F. Jimenez-Esteban
Context: A large fraction of otherwise similar asymptotic giant branch stars (AGB) do not show OH maser emission. As shown recently, a restricted lifetime may give a natural explan…
Nebular emission lines in IRAS 17347-3139
F. M. Jiménez-Esteban, J. V. Perea-Calderón, O. Suárez +2
We report the detection of nebular emission lines in the optical and mid-infrared spectra of IRAS 17347-3139, a heavily obscured OH/IR star which may be rapidly evolving from the A…
Stellar evolution and the 'O-rich AGB sequence'
F. M. Jimenez-Esteban, D. Engels, P. Garcia-Lario
The `O-rich AGB sequence' is a well defined area occupied by oxygen-rich AGB stars (OH/IR) in the IRAS two-colour diagram [12]-[25] vs [25]-[60]. This sequence is interpreted in te…
An infrared study of galactic OH/IR stars. I. An optical/near-IR atlas of the Arecibo sample
F. M. Jiménez-Esteban, L. Agudo-Mérida, D. Engels +1
In this paper we present optical and near-infrared finding charts, accurate astrometry (~1") and single-epoch near-infrared photometry for 371 IRAS sources, 96% of those included i…
