TL;DR: In this article, the authors report a nearly uninterrupted time series photometric observations of the DBV star GD 358 acquired with the Whole Earth Telescope (WET) during May 23rd to June 8th, 2000.
VLT spectroscopy and non-LTE modeling of the C/O-dominated accretion disks in two ultracompact X-ray binaries
TL;DR: In this paper, the authors presented new medium-resolution high-S/N optical spectra of the ultracompact low-mass X-ray binaries 4U 0614+091 and 4U 1626-67, taken with the ESO Very Large Telescope.

TL;DR: In this article, the authors used all available WET photometric data from 1983, 1985, 1989, 1993 and 2002 to identify 76 additional pulsation periods and increasing to 198 the number of known pulsation modes in PG 1159-035, the largest number of modes detected in any star besides the Sun.
Non-LTE models for the gaseous metal component of circumstellar discs around white dwarfs
TL;DR: In this article, the vertical structure and line spectra of the first object for which a gas disc was discovered (SDSS J122859.93+104032.9).

TL;DR: In this article, the authors report on the analysis of 34 years of photometric observations of the pulsating helium atmosphere white dwarf GD358 and present evidence that these 15 modes are ell = 1 modes, 13 of which belong to a consecutive sequence in radial overtone k.
