UBVRI photometric sequences for symbiotic stars
نویسنده
چکیده
Deep, wide-range and accurate UBVRI photometric sequences have been established around more than 80 symbiotic stars, to assist current photometry as well as measurement of old photographic plates. Sequences for 40 symbiotic stars have already been published; the observations for the others have already been secured.

UBV(RI)C photometric comparison sequences for symbiotic stars
We present accurate UBV(RI)C photometric sequences around 20 symbiotic stars. The sequences extend over wide brightness and color ranges, and are suited to cover quiescence as well as outburst phases. The sequences are intended to assist both present time photometry as well as measurement of photographic plates from historical archives.
متن کاملUBV(RI)C photometric comparison sequences for symbiotic stars. II
We present accurate UBV(RI)C photometric sequences for an additional 20 symbiotic stars. As for the 20 targets of Paper I, the sequences extend over wide brightness and color ranges, and are suited to cover both quiescence and outburst phases. The sequences are intended to assist both present time photometry as well as measurement of photographic plates from historical archives.
متن کاملPhotometric Catalog of Sym - Biotic Stars
We present a multi-epoch, accurate UBVRcIc photometric catalog of 83 symbiotic stars and related objects, measured while calibrating the Henden and Munari (2000, 2001, 2006) photometric sequences around them. The vast majority of the observations where collected in the time interval between October 19, 1998 to April 21, 2002 with the 1.0-m Ritchey-Chrétien telescope of the U. S. Naval Observato...
متن کاملWFC3/UVIS Photometric Transformations
We provide photometric transformation coefficients for converting magnitudes from the native WFC3/UVIS filter passbands to Johnson/Cousins UBVRI passbands in ABMAG, STMAG and VEGAMAG system. The transformation coefficients have been calculated both for UVIS1 and UVIS2 chips, for stars of various spectral types and a range blackbody temperatures using synthetic stellar/black-body models. We also...
متن کاملEmpirical Color Transformations Between SDSS Photometry and Other Photometric Systems
Aims. We present empirical color transformations between the Sloan Digital Sky Survey (SDSS) ugriz photometry and Johnson-Cousins UBVRI system and Becker’s RGU system, respectively. Owing to the magnitude of data that is becoming available in the SDSS photometric system it is particularly important to be able to convert between this new system and traditional photometric systems. Unlike earlier...
