A Sr-Rich Star on the Main Sequence of Omega Centauri [PDF]
, 2006 Abundance ratios relative to iron for carbon, nitrogen, strontium and barium are presented for a metal-rich main sequence star ([Fe/H]=--0.74) in the globular cluster omega Centauri. This star, designated 2015448, shows depleted carbon and solar nitrogen,

CD -24_17504 revisited: a new comprehensive element abundance analysis [PDF]
, 2015 With [Fe/H] ~ -3.3, CD -24_17504 is a canonical metal-poor main sequence turn-off star. Though it has appeared in numerous literature studies, the most comprehensive abundance analysis for the star based on high resolution, high signal-to-noise spectra ...

Thermal design and analysis of high power star sensors
Case Studies in Thermal Engineering, 2015 The requirement for the temperature stability is very high in the star sensors as the high precision needs for the altitude information. Thermal design and analysis thus is important for the high power star sensors and their supporters.

SDSS J142625.71+575218.3: A Prototype for A New Class of Variable White Dwarf [PDF]
, 2008 We present the results of a search for pulsations in six of the recently discovered carbon-atmosphere white dwarf ("hot DQ") stars. On the basis of our theoretical calculations, the star SDSS J142625.71 + 575218.3 is the only object expected to pulsate ...

The influence of initial orbital period on helium and carbon-oxygen core masses in massive case a binary systems with low accretion efficiency [PDF]
Serbian Astronomical Journal, 2022 The evolutionary models of 33 massive Case A binary systems in mass range from 30M⊙ to 40M⊙ with initial orbital periods of 3, 4 and 5 days, accretion efficiency of 10% and at the solar metallicity are presented. The models are obtained with the

Tracing the origin of neutron-capture elements in the metalpoor star HE 1244-3036 [PDF]
EPJ Web of ConferencesWe present results from a detailed abundance analysis of a star HE 1244-3036, based on a high resolution (R ∼ 50000) SUBARU/HDS spectrum. The wavelength coverage is from 3510 to 5310 Å. Our estimated metallicity [Fe/H] ∼ −2.5 and carbon abundance ([C/Fe]
