Abstract:
Long-term (1984-2008) JHKLM photometry for 254 objects is presented.
The observations were carried out in the standard JHKLM photometric
system using an original method and a modern IR photometer designed
and built at the Sternberg Astronomical Institute. Our program of
studies included searches for and studies of relatively hot
circumstellar dust envelopes.
Description:
Our observations were carried out on the 125-cm telescope of the
Crimean Laboratory of the Sternberg Astronomical Institute (SAI) of
Moscow State University using a single-channel InSb photometer with a
standard JHKLM photometric system.
