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 کاملUBV(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 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 کاملThe uBVI Photometric System . II . Standard Stars
Paper I of this series described the design of a CCD-based photometric system that is optimized for ground-based measurements of the size of the Balmer discon-tinuity in stellar spectra. This " uBVI " system combines the Thuan-Gunn u filter with the standard Johnson-Kron-Cousins BVI filters, and it can be used to discover luminous yellow supergiants in extragalactic systems and post-asymptotic-...
متن کاملA catalogue of symbiotic stars
We present a new catalogue of symbiotic stars. In our list we include 188 symbiotic stars as well as 28 objects suspected of being symbiotic. For each star, we present basic observational material: coordinates, V and K magnitudes, ultraviolet (UV), infrared (IR), X-ray and radio observations. We also list the spectral type of the cool component, the maximum ionization potential observed, refere...
