Draco C1 is a known symbiotic binary star system composed of a carbon red giant and a hot, compact companion—likely a white dwarf—belonging to the Draco dwarf...
Infrared and visible photometry of the RS CVn-star II Peg
Infrared photometry in J,H,K,L,M bands carried out in different years from 1983 to 1986, and U,B,V,R,I quasi-simultaneous to 1984 are presented. Although the...
JHKLM photometry is presented for the close binary systems W UMa, U Sge and Beta-Lyr, and two systems, Eta-Gem and RR UMi, containing late-type variable...
Infrared photometry of open clusters - The main sequence of NGC 752
New infrared photometry of a sample of 39 stars in the open cluster NGC 752 is presented. These observations confirm the bimodality of the main sequence...
Infrared photometry of the RS CVn short-period systems - XY UMa and WY CNC
Infrared J and K light curves of two RS CVn short-period systems, XY UMa and WY Cnc, are presented. Both systems show similar variability in the infrared to...
Infrared photometry of upper main sequence stars in M39
Infrared photometry of 19 Main sequence stars in the open cluster M39 is presented. Infrared-infrared and optical-infrared color-color and color-magnitude...
Infrared Spectroscopy Of V404 CYGNI. Limits On The Accretion Disc Contamination
We have obtained for the first time 2.10 - 2.45 micron infrared spectra of soft X-ray transient V404 Cygni. We determine a 95 percent confidence upper limit to...
Binary models of symbiotic stars are discussed, analyzing the results of recent IR observations. It is indicated that a binary must have component masses of...
MOA-2006-BLG-074: Recognizing Xallarap Contaminants in Planetary Microlensing
MOA-2006-BLG-074 was selected as one of the most promising planetary candidates in a retrospective analysis of the MOA collaboration: its asymmetric high...
