The Origins of Lithium Enhancement in Polluted White Dwarfs
Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4
The bulk abundances of exoplanetesimals can be measured when they are accreted by white dwarfs. Recently, lithium from the accretion of exoplanetesimals was detected in relatively…
A Pulsational Model for the Orthogonal Polarization Modes in Radio Pulsars
J. Christopher Clemens, R. Rosen
In an earlier paper, we introduced a model for pulsars in which non-radial oscillations of high spherical degree (\el) aligned to the magnetic axis of a spinning neutron star were…
Ensemble Characteristics of the ZZ Ceti stars
Anjum S. Mukadam, M. H. Montgomery, D. E. Winget +2
We present the observed pulsation spectra of all known non-interacting ZZ Ceti stars (hydrogen atmosphere white dwarf variables; DAVs) and examine changes in their pulsation proper…
The Peculiar Pulsations of PY Vul
Susan E. Thompson, J. C. Clemens, M. H. van Kerkwijk +2
The pulsating white dwarf star PY Vul (G~185-32) exhibits pulsation modes with peculiar properties that set it apart from other variable stars in the ZZ Ceti (DAV) class. These pec…
Mode identification of Pulsating White Dwarfs using the HST
S. O. Kepler, E. L. Robinson, D. Koester +3
We have obtained time-resolved ultraviolet spectroscopy for the pulsating DAV stars G226-29 and G185-32, and for the pulsating DBV star PG1351+489 with the Hubble Space Telescope F…
