Observations in regions of Cassiopeia, Gemini, and Monoceros with the Glazar space telescope
Observations at 1640 A of regions in Cassiopeia, Gemini, and Monocerosmade with the Glazar space telescope are presented; 7, 11, 13, and 35early-type stars brighter than about 9 mag were detected in the observedregions. The distribution of dust matter in the corresponding regions isstudied. It is determined that companions of HD 4442, 4797, and BD + 62deg 2225 are subdwarfs of sdB - sdO types; the hot companion of HD220102 may be of the type from B8 Ib-II to sdB. It is shown that HD 5233and 261490 are probably embedded in dense circumstellar envelopes.
| Polarization of the light of the stars in the association MON R1
New observations of polarization of the light of the stars in thereflection nebula association Mon R1 are given. Of 17 stars investigatedin the B photometric system, nine are cores of reflection nebulas. Thestar VY Mon is found to have a large polarization. The manner in whichthe polarization of the stars and the structure of the nebulas arerelated to the magnetic field of the cloud in which they are situated isdiscussed.
