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...
Elemental Abundances of Planet-Host Cool Dwarfs: Clues on Planet Formation and Evolution
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...
Elementary Theory of Scattering Polarization in Complex Atoms
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...
Eliminating Virtual Impactors with Mega-Precovery (VIMP)
Continuing the EURONEAR data-mining projects, we developed the VIMP tool to search for Virtual Impactor asteroids (VIs) using our Mega-Precovery archival image...
Elliptical Galaxies and the Continuity of the Hubble Sequence First Results of the ESO Key Programme "Towards a Physical Classification of Early-Type Galaxies"
