TL;DR: In this paper, the relative abundances of 17 elements in the atmosphere of the white dwarf star GD 362, material that, very probably, was contained previously in a large asteroid or asteroids with composition similar to the Earth-Moon system, were reported.

TL;DR: In this paper, the authors performed a comprehensive ground-based observational program aimed at characterizing the circumstellar material orbiting three single white dwarf stars previously known to possess gaseous disks.

TL;DR: In this article, the authors performed a comprehensive ground-based observational program aimed at characterizing the circumstellar material orbiting three single white dwarf stars previously known to possess gaseous disks.

TL;DR: The first unambiguous example of a new class of first-ascent giant stars that are actively accreting gas and dust and that are surrounded by substantial dusty disks was identified in this article.

TL;DR: In this article, a multi-wavelength observational campaign demonstrating some of the remarkable properties of the infrared-bright variable star BP Psc has been carried out, demonstrating that the gas accretion in conjunction with narrow bipolar jets and Herbig-Haro objects is consistent with classification of BPPsc as a pre-main-sequence star, as postulated in most previous studies.
