We present JHK photometry and spectroscopy for a sample of newly identified L and T dwarfs from the Sloan Digital Sky Survey (SDSS) and known dwarfs from the SDSS and the Two Micron All Sky Survey (2MASS). Spectral classification has been carried out

We report on long-term K band photometry of the galactic microquasar GRS 1915+105 since March 1999. We see variations of more than 1 mag, which are seemingly correlated with variations in X-ray intensity and spectral slope.

A pair of spectroscopically nearly identical M supergiant stars were proposed [1] as possible counterparts to SGR 1900+14 based on positional coincidences with gamma-ray and x-ray localizations. Whether these stars or the nearby fading radio source [

Intermediate infrared and (V-I) photometry is presented for 14 reddened B- and A-type stars in Ori OB1 (Belt). From a color-difference analysis, R (the ratio of total-to-selective absorption) is found to be uniform across the subgroup, and calculated
