The physics of infrared emission processes is examined, taking into account black body radiation, radiation from dust particles, thermal plasma emission...

While the shape of the extinction curve in the infrared is considered to be set and the extinction ratios between infrared bands are usually taken to be...

In our search, started in February, 1994, for JHK excess fluxes among the hot subdwarf population as an indicator for the presence of binary companions, results...

Chemical abundances are presented for 25 M31 globular clusters (GCs), based on moderately high resolution (R = 22,500) H-band integrated light (IL) spectra from...

We report experimental oscillator strengths for 28 infrared Fe I transitions, for which no previous experimental values exist. These transitions were selected...

We present the first light curves in the infrared j and K filters, obtained in different runs during 1990, 1991, and 1994. The solutions of these IR light...

We present the first infrared (IR) light curves in the J, H and K bands of δ Lib obtained at different observing runs from 1994 to 1998. These IR light curves...

We present the first light curves in the infrared J, H, and K bands of UX Her and analyze them together with published light curves in B and V in order to...

We present the first results of a study of the morphology, kinematics and ionization structure of infrared (IR) mergers/quasi-stellar objects (QSOs) with...
