White dwarf planets

EPJ Web of Conferences, 2013
The recognition that planets may survive the late stages of stellar evolution, and the prospects for finding them around White Dwarfs, are growing. We discuss two aspects governing planetary survival through stellar evolution to the White Dwarf stage ...

Asymptotic Giant Branch variables in the Galaxy and the Local Group [PDF]

Astrophysics and Space Science, 2012
AGB variables, particularly the large amplitude Mira type, are a vital step on the distance scale ladder. They will prove particularly important in the era of space telescopes and extremely large ground-based telescopes with adaptive optics, which will be optimized for infrared observing.

Mira Variables Based on Emission Lines in LAMOST DR9

The Astrophysical Journal
We present a sample of 335 Mira variables, extracted from DR9 of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. These variables are characterized by the Balmer emissions (H δ , H γ , H β , and H α ) and the metal emissions

Introduction to Asymptotic Giant Branch Stars

Journal of Physics: Conference Series, 2016
A brief introduction on the main characteristics of the asymptotic giant branch stars (briefly: AGB) is presented. We describe a link to observations and outline basic features of theoretical modeling of these important evolutionary phases of stars. The most important aspects of the AGB stars is not only because they are the progenitors of white dwarfs,

The Star Formation History of WLM from Asymptotic Giant Branch Stars and the Discovery of a Candidate Accreted System in its Outer Disk

The Astrophysical Journal
We measure the star formation history (SFH) of Local Group dwarf galaxy Wolf–Lundmark–Melotte (WLM) using wide-area (∼4 half-light radii) ground-based near-infrared (NIR) imaging of bright ( M _J

The Asymptotic Giant Branches of GCs: Selective Entry Only

, 2013
The handful of available observations of AGB stars in Galactic Globular Clusters suggest that the GC AGB populations are dominated by cyanogen-weak stars. This contrasts strongly with the distributions in the RGB (and other) populations, which generally show a 50:50 bimodality in CN band strength.

TIC 295741342: A Triply Eclipsing Triple Star System with a Giant Tertiary

The Astrophysical Journal
We present the discovery and characterization of TIC 295741342, a triply eclipsing triple star system with a giant tertiary. The eclipsing binary consists of two similar main-sequence stars in a 4.75 day orbit. The binary is in a 412.8 day orbit with the
