An infrared study of galactic OH/IR stars. II. The "GLMP sample" of red oxygen-rich AGB stars Jimenez-Esteban F.M., Garcia-Lario P., Engels D., Perea Calderon J.V. <Astron. Astrophys. 446, 773 (2006)> =2006A&A...446..773J
ADC_Keywords: Infrared sources ; Stars, variable ; Photometry, infrared Keywords: stars: AGB and post-AGB Abstract: We present optical and near-infrared finding charts taken from the DSS and 2MASS surveys of 94 IRAS sources selected from the GLMP catalogue, and accurate astrometry (∼0.2") for most of them. Selection criteria were very red IRAS colours representative for OH/IR stars with optically thick circumstellar shells and the presence of variability according to the IRAS variability index (VAR>50). The main photometric properties of the stars in this `GLMP sample' are presented, discussed and compared with the correspondent properties of the `Arecibo sample' of OH/IR stars studied nearlier. We find that 37% of the sample (N=34) has no counterpart in the 2MASS, implying extremely high optical depths of their shells. Most of the sources identified in the 2MASS are faint (K≳8) and are of very red colour in the near-infrared, as expected. The brightest 2MASS counterpart (K=5.3mag) was found for IRAS18299-1705. Its blue colour H-K=1.3 suggests that IRAS18299-1705 is a post-AGB star. Few GLMP sources have faint but relatively blue counterparts. They might be misidentified field stars or stars that recently experienced a drop of their mass loss rates. The `GLMP sample' in general is made of oxygen-rich AGB stars, which are highly obscured by their circumstellar shells. They belong to the same population as the reddest OH/IR stars in the `Arecibo sample'. Description: Table3 contains the 2MASS coordinates. It also contains the relative distance from the near infrared counterpart found to the original IRAS coordinates. When available, the distance of the associated MSX counterparts to the IRAS position is also provided for comparison. Table4 contains the MSX coordinates. It also contains the relative distance from the MSX counterpart found to the original IRAS coordinates. Table5 contains the near infrared magnitudes (or lower magnitude limits) for the GLMP sources (Garcia-Lario et al., see Cat. J/A+AS/126/479) File Summary:
