P-STARS

International Journal of Modern Physics D, 2004
P-Stars are a new class of compact stars made of up and down quarks in β-equilibrium with electrons in an Abelian chromomagnetic condensate. We show that P-Stars are able to account for compact stars with R≲6 Km , as well as stars with radius comparable with canonical Neutron Stars.

Magnetic stars from a FEROS cool Ap star survey [PDF]

, 2011
New magnetic Ap stars with split Zeeman components are presented. These stars were discovered from observations with the Fibre-fed Extended Range Optical Spectrograph (FEROS) spectrograph at the European Southern Observatory (ESO) 2.2-m telescope. 15 new

Chemical and kinematical properties of BSSs and HB stars in NGC 6397

, 2012
We used three sets of high-resolution spectra acquired with the multifiber facility FLAMES at the Very Large Telescope of the European Southern Observatory to investigate the chemical and kinematical properties of a sample of 42 horizontal branch (HB ...

Non-radial Oscillation Modes of Compact Stars with a Crust [PDF]

, 2017
Oscillation modes of isolated compact stars can, in principle, be a fingerprint of the equation of state (EoS) of dense matter. We study the non-radial high-frequency l=2 spheroidal modes of neutron stars and strange quark stars, adopting a two-component

The puzzle of the CNO isotope ratios in AGB carbon stars

, 2016
Previous determinations of the oxygen isotopic ratios in AGB carbon stars were at odds with the existing theoretical predictions. We aim to redetermine the oxygen ratios in these stars using new spectral analysis tools and further develop discussions on ...

Properties of massive stars in four clusters of the VVV survey

, 2015
The evolution of massive stars is only partly understood. Observational constraints can be obtained from the study of massive stars located in young massive clusters.

The Effect of Dark Matter on the First Stars: A New Phase of Stellar Evolution

, 2007
Dark matter (DM) in protostellar halos can dramatically alter the current theoretical framework for the formation of the first stars. Heat from supersymmetric DM annihilation can overwhelm any cooling mechanism, consequently impeding the star formation ...

STAR POLYMERS [PDF]

Condensed Matter Physics, 2002
It is our great pleasure to present a collection of papers devoted to theoretical, numerical, and experimental studies in the field of star polymers. Since its introduction in the early 80-ies, this field has attracted increasing interest and has become an important part of contemporary polymer physics.
