A SEARCH FOR FIELD HORIZONTAL-BRANCH STARS NEAR THE SOUTH GALACTIC POLE
(IOP PUBLISHING LTD, 2010)
Searches for field horizontal-branch (FHB) stars in the halo of the Galaxy in the past have been carried out by several techniques, such as objective-prism surveys and visual or infrared photometric surveys. By choosing ...
Constraints on helium enhancement in the globular cluster m4 (NGC 6121): the horizontal branch test
(American Astronomical Society, 2020)
Study of the impact of the post-MS evolution of the host star on the orbits of close-in planets. II. A giant planet in a close-in orbit around the RGB star HIP 63242
(EDP Sciences, 2013)
Context. More than 40 planets have been found around giant stars, revealing a lack of systems orbiting interior to ∼0.6 AU. This
observational fact contrasts with the planetary population around solar-type stars and has ...
Pulsational instabilities driven by the mechanism in hot pre-horizontal branch stars: I. the hot-flasher scenario
(EDP Sciences, 2018-06)
Context. The mechanism is a self-excitation mechanism of stellar pulsations that acts in regions inside the star where nuclear burning takes place. It has been shown that the mechanism can excite pulsations in models of ...
