I report on a critical analysis of the scenario of electroweak baryogenesis mediated by nonsuperconducting cosmic strings. This mechanism relies upon...

High-resolution spectra of the program stars were obtained during the period 2002 December-2004 June at the Harlan J. Smith 2.7-m telescope of the W.J. McDonald...

Here, we discussed our recent results of elemental abundance survey of Galactic disk based on 181 F- and G-type dwarfs (published by Reddy et al. 2003, MNRAS...

Since a large fraction of stars harbor at least one planet, the formation of planets around newly forming stars appears to be a common phenomenon. Planet cores...

Scattering polarization in complex atoms poses interesting theoretical problems and is interesting for diagnostic plasma purposes. Here, an elementary theory on...

Having acquired since July, 1989, a complete 11-year solar cycle of full disk data, the IRIS++ network has now made available to anyone the longest helioseismic...

Continuing the EURONEAR data-mining projects, we developed the VIMP tool to search for Virtual Impactor asteroids (VIs) using our Mega-Precovery archival image...
