2014/12/9
This thesis presents a large scale search for new low mass members of the Pleiades cluster using near-infrared photometry from the Two Micron All Sky Survey and proper motions derived from digitized P...
Stark Broadening of Carbon and Oxygen Lines in Hot DQ White Dwarf Stars: Recent Results and Applications
stars: atmospheric parameters – broadening: Stark
font style='font-size:12px;'>
2011/10/9
White dwarf stars are traditionally found to have surface compositions made primarily of hydrogen or helium. However, a new family has recently been uncovered, the so-called Hot DQ white dwarfs, which...
Towards Quark Deconfinement in Neutron Stars via Spindown: Gravitational Waves or Magnetic Braking?
Quark Deconfinement Neutron Stars Gravitational Waves Magnetic Braking

2011/9/28
A phase of interacting quark matter can arise inside the dense core of isolated neutron stars when they have been sufficiently spun down from their initial rapidly rotating configuration. In this work...
Nucleosynthesis origin of PG 1159 stars, Sakurai's object and of rare subclasses of presolar grains
Nucleosynthesis subclasses presolar grains

2011/9/27
We discuss theoretical AGB predictions for hydrogen-deficient PG 1159 stars and Sakurai's object, which show peculiar enhancements in He, C and O, and how these enhancements may be understood in the f...
Relation between a Function of the Right Ascension and the Angular Distance to the Vertex for Hyades Stars
Moving clusters Hyades cluster open clusters Hyades astrometric and kinematic
font style='font-size:12px;'>
2009/5/14
In this paper, relation was developed for Hyades stars between
a function of the right ascensions and the angular distances from the vertex.
The precision criteria of this relation are very satisfac...
On Surface Tension for Compact Stars
Relativity pulsars equation of state
