O consumo da experiência na ficção seriada televisiva: Gilmore Girls e a cidade de Stars Hollow
Lumina, 2017 Neste artigo, analisamos a importância da cidade de Stars Hollow na experiência de consumo da série televisiva Gilmore Girls a partir de duas premissas. A primeira é que a pequena cidade fictícia localizada no estado de Connecticut se configura como uma ...

New DA white dwarf models for asteroseismology of ZZ Ceti stars [PDF]
Astronomy & Astrophysics, 2022 Context. Asteroseismology is a powerful tool to infer the evolutionary status and chemical stratification of white dwarf stars, and to gain insight into the physical processes that lead to their formation.

ON THE KINEMATICS OF THE VARIABLE DA STARS.
Publications of the Astronomical Society of the Pacific, 1978 We examine the kinematics of the known variable DA white dwarfs relative to a sample of observed nonvariable DA white dwarfs in the same color range. The variable DA stars do not form a kinematically distinct group relative to the nonvariable stars. Possible implications based upon the kinematics are briefly discussed.

A GRAVITATIONAL REDSHIFT DETERMINATION OF THE MEAN MASS OF WHITE DWARFS. DA STARS [PDF]
The Astrophysical Journal, 2010 We measure apparent velocities (vapp) of the Hα and Hβ Balmer line cores for 449 non-binary thin disk normal DA white dwarfs (WDs) using optical spectra taken for the European Southern Observatory SN Ia progenitor survey (SPY).

Gravity and limb-darkening coefficients for compact stars: DA, DB, and DBA eclipsing white dwarfs [PDF]
Astronomy & Astrophysics, 2020 Context. The distribution of the specific intensity over the stellar disk is an essential tool for modeling the light curves in eclipsing binaries, planetary transits, and stellar diameters through interferometric techniques, line profiles in rotating ...

A Spectroscopic Survey in the EUV of the “Coolest” Hot DA Stars [PDF]
International Astronomical Union Colloquium, 1996 We present an analysis of the extreme ultraviolet (EUV) spectroscopy of a sample of 10 DA white dwarfs observed by the Extreme Ultraviolet Explorer (EUVE). We have selected white dwarfs cooler than about 50,000 K and with presumably low heavy element abundances.

Estimating Atmospheric Parameters of DA White Dwarf Stars with Deep Learning [PDF]
The Astronomical Journal, 2020 The determination of atmospheric parameters of white dwarf stars (WDs) is crucial for researches on them. Traditional methodology is to fit the model spectra to observed absorption lines and report the parameters with the lowest χ2 error, which strongly ...

Thirty-two New Bright ZZ Ceti Stars from TESS: Adding Cycles 4 and 5 [PDF]
The Astrophysical JournalAnalyzing all 120 s and 20 s light curves obtained by the TESS satellite up to Sector 69—the end of the fifth year of observations—for all known white dwarfs and white dwarf candidates up to G = 17.5 mag, we report the discovery of 32 new pulsating DA ...

The Astrophysical JournalBinaries of two white dwarfs (WDs) are an important class of astrophysical objects that help us reconstruct the complex processes involved in stellar evolution and are theorized to lead to Type Ia supernovae.
