So far, detailed stellar population studies, based on the absorption line strengths have been concentrated mainly in the optical spectral range. In this work...

In recent years, some extremely red brown dwarfs have been discovered. They were believed to have a low surface gravity, but many of their spectral...

We present information on two spectral lines, Fe I 6173 Å and Ni I 6768 Å, that were candidates for use in the Helioseismic and Magnetic Imager (HMI) instrument...

Optical microvariability (OM, small amplitude variations in time scales from minutes to hours) in radio-quiet quasars (RQQ) may be as frequent as in radio-loud...

Trans-Neptunian Objects (TNOs) harbor some of the most pristine materials in the Solar System. JWST observations of TNOs from Cycle 1's campaign of "Discovering...

We have computed the Band Area Ratio (BAR) and Band I Center parameters, following the method by Cloutis et al. (1986) and Gaffey et al. (1993) for all the...

We present results of the X-ray spectral analysis of the ˜370 ksec deep survey obtained with XMM-Newton on the Chandra Deep Field South (CDFS). Using sample of...
