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...

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 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 19 Main sequence stars in the open cluster M39 is presented. Infrared-infrared and optical-infrared color-color and color-magnitude...

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 was selected as one of the most promising planetary candidates in a retrospective analysis of the MOA collaboration: its asymmetric high...

Recent observational and theoretical investigations of the sun and sunlike stars and of galactic structure and evolution are discussed in reviews and reports...
