Faint star counts with HST
We describe a program of star counts in the range 19 ∼< I ∼< 26 made with the WFPC cameras aboard the Hubble Space Telescope. Red (V − I > 1.0) stars at these magnitudes are primarily disk and spheroid M dwarfs. The stars are found both on dedicated images as part of the parallel program and by using appropriate archive data. We measure the faint end of the luminosity functions of the disk and ...
متن کاملDissolving star cluster candidates
We present a list of 34 neglected entries from star cluster catalogues located at relatively high galactic latitudes (|b| > 15) which appear to be candidate late stages of star cluster dynamical evolution. Although underpopulated with respect to usual open clusters, they still present a high number density contrast as compared to the galactic field. This was verified by means of (i) predicted m...
متن کاملFaint star counts in the near - infrared
Received ; accepted – 2 – ABSTRACT We discuss near-infrared star counts at the Galactic pole with a view to guiding the NGST and ground-based NIR cameras. Star counts from deep K-band images from the CFHT are presented, and compared with results from the 2MASS survey and some Galaxy models. With appropriate corrections for detector artifacts and galaxies, the data agree with the models down to ...
متن کاملSpectroscopic Observations of Twenty - one Faint Cataclysmic Variables Candidates ⋆
We provide the first minimum light spectroscopic observations for 21 previously known or suspected faint cataclysmic variable candidates. The sources were selected from the Downes et al. (2001) living edition catalog and the identified candidates have minimum light magnitudes of V∼18-22. We confirm 15 of the candidates to be cataclysmic variables.
متن کاملDENIS and ISOGAL properties of variable star candidates in the Galactic Bulge
Repeated DENIS observations (summer 1996 & 1998) in the J (1.25 μm) and the KS (2.15 μm) bands are used to look for variable stars. We present two catalogues of ∼ 1000 probable variables in an area of ∼ 4 deg2 of the inner galactic bulge. The first one contains ∼ 720 variable star candidates which show variability in J and KS while the second consists of sources only observed to be variable in ...
