UBV(RI)C photometric comparison sequences for symbiotic stars
نویسندگان
چکیده
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.

UBV(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 کاملUBVRI photometric sequences for symbiotic stars
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.
متن کاملRI CCD sequences for wide - field surveys – II . UBV R sequences at δ = − 30 ◦
We present results from a continuing campaign to secure deep multi-colour CCD sequences for photometric calibration in UK Schmidt fields with galactic latitudes |b| > 50 •. In this paper we present U BV R photometry in 12 fields and BR photometry in a further 14 fields observed within UK Schmidt survey fields centred at δ = −30 •. Photometric errors are at the 0.05 level at 20.2, 21, 20.5 and 2...
متن کاملDatabase of Geneva stellar evolution tracks and isochrones for ( UBV ) J ( RI ) C JHKLL ′ M , HST - WFPC 2 , Geneva and Washington photometric systems
We have used an updated version of the empirically and semi-empirically calibrated BaSeL library of synthetic stellar spectra of Lejeune et al. (1997, 1998) and Westera et al. (1999) to calculate synthetic photometry in the (UBV)J (RI)C JHKLL M, HST-WFPC2, Geneva, and Washington systems for the entire set of non-rotating Geneva stellar evolution models covering masses from 0.4– 0.8 to 120–150 M...
