Laboratory Measurements Of White Dwarf Photospheric Spectral Lines: H Beta

Falcon, Ross E.; Rochau, G. A.; Bailey, J. E.; Gomez, Thomas A.; Montgomery, Michael H.; Winget, D. E.; Nagayama, T. (2015-06)

We spectroscopically measure multiple hydrogen Balmer line profiles from laboratory plasmas to investigate the theoretical line profiles used in white dwarf (WD) atmosphere models. X-ray radiation produced at the Z Pulsed ...

A Gravitational Redshift Determination Of The Mean Mass Of White Dwarfs: DBA And DB Stars

Falcon, Ross E.; Winget, D. E.; Montgomery, Michael H.; Williams, Kurtis A. (2012-10)

We measure apparent velocities (nu(app)) of absorption lines for 36 white dwarfs (WDs) with helium-dominated atmospheres-16 dbAs and 20 dbs-using optical spectra taken for the European Southern Observatory SN Ia progenitor ...
