Synthetic photometry from ATLAS9 models in the UBV Johnson system
Several grids of synthetic UBV color indices computed in the Johnson system and based on ATLAS9 atmospheric models are compared and discussed. We present synthetic colors which differ from those computed by Kurucz (1995) only for the convective models and for a very small shift of the zero-points. We compare these colors, called C97, with colors computed by Kurucz (1993a), Kurucz (1995) (K95), ...
متن کاملUBV JHKLM photometry and modeling of R Coronae Borealis
We present the results of UBV JHKLM photometry of RCrB spanning the period from 1976 to 2001. Studies of the optical light curve have shown no evidence of any stable harmonics in the variations of the stellar emission. In the L band we found semi-regular oscillations with the two main periods of ∼ 3.3 yr and ∼ 11.9 yr and the full amplitude of ∼ 0. 8 and ∼ 0. 6, respectively. The colors of the ...
متن کاملMultiaperture UBV RIzJHK Photometry of Galaxies in the Coma Cluster
We present a set of UBV RIzJHKs photometry for 745 J +H band selected objects in a 22.5 × 29.2 region centered on the core of the Coma cluster. This includes 516 galaxies and is at least 80% complete to H = 16, with a spectroscopically complete sample of 111 cluster members (nearly all with morphological classification) for H < 14.5. For each object we present total Kron (1980) magnitudes and a...
متن کاملUBV RI CCD photometry of the OB associations
We report the first deep UBV RI CCD photometry of 2460 stars in the field of two poorly studied OB associations Bochum 1 and Bochum 6. We selected 15 and 14 probable members in Bochum 1 and Bochum 6 respectively using photometric criteria and proper motion data of Tycho 2. Our analysis indicates variable reddening having mean value of E(B − V ) = 0.47±0.10 and 0.71±0.13 mag for Bochum 1 and Boc...
متن کاملUBV ( RI ) C and uvby photometry of HD 81410 and starspot distribution in RS CVn objects ?
We present UBV RI and uvby photometry of HD 81410 obtained on a total of 40 nights during 1987–90, and an analysis of its long-term photometric behaviour. The star is found to show two well-separated minima in its light curve most of the time; probably there are two preferred effective longitudes about which spots are mainly formed. The migration of the phase of the light minimum usually seen i...
