Theoretical Interpretation of the Measurements of the Secondary Eclipses of TrES-1 and HD209458b
TL;DR: In this article, the authors calculate the planet-star flux-density ratios as a function of wavelength from 0.5 microns to 25 microns for the transiting extrasolar giant planets TrES-1 and HD209458b and compare them with the recent Spitzer/IRAC-MIPS secondary eclipse data.

Paul Dobbie,Ralf Napiwotzki,Matthew R. Burleigh,Kurtis A. Williams,Rob Sharp,Martin A. Barstow,S. L. Casewell,Ivan Hubeny +7 more
TL;DR: In this article, a photometric and spectroscopic study of the white dwarfs candidate members of the intermediate age open clusters NGC3532 and NGC2287 is presented.

FUSE and HST/STIS far-ultraviolet observations of AM Herculis in an extended low state
TL;DR: In this article, the authors obtained FUSE and HST/STIS time-resolved spectroscopy of the polar AM Herculis during a deep low state, and determined the white dwarf parameters from a spectral fit to the faint phase data, when the hot spot is self-eclipsed.

Non-LTE Model Atmospheres for Late-Type Stars I. A Collection of Atomic Data for Light Neutral and Singly-Ionized Atoms
TL;DR: In this article, a set of model atoms and singly ionized ions for use in building NLTE model atmospheres is presented, combining measured energy levels, critically-compiled line transition probabilities, and resonance-averaged calculations of photoionization cross-sections.

A near-IR spectroscopic search for very-low-mass cool companions to notable DA white dwarfs
Paul Dobbie,Matthew R. Burleigh,Andrew J. Levan,Martin A. Barstow,Ralf Napiwotzki,Jay B. Holberg,Ivan Hubeny,Steve B. Howell +7 more
TL;DR: In this article, a detailed near-IR spectroscopic analysis of eight notable white dwarfs, predominantly of southern declination, was carried out and the spectral type of a putative late-type companion to each degenerate was determined.
