A far-ultraviolet study of the hot white dwarf in the dwarf nova WW Ceti
(2006-05)
We present a synthetic spectral analysis of IUE archival and FUSE (Far Ultraviolet Spectroscopic Explorer) far-UV spectra of the peculiar dwarf nova WW Cet. During the quiescence of WW Cet, a white dwarf with T wd ∼ 26,000 ...
Iron in hot DA white dwarfs
(2006-12-01)
We present a study of the iron abundance pattern in hot, hydrogen-rich (DA) white dwarfs. The study is based on new and archival far-ultraviolet spectroscopy of a sample of white dwarfs in the temperature range 30,000 K ≲ ...
Origin of heavy ions in upstream events near the earth's bow shock
(2006-09-20)
We have surveyed the ∼20-160 keV/nucleon heavy ion composition of 2102 upstream events observed by the Wind/STEP instrument near the Earth's bow shock over a complete solar cycle from day 325, 1994 through day 90, 2006. ...
The role of interplanetary scattering in western hemisphere large solar energetic particle events
(2006-08-10)
Using high-sensitivity instruments on the ACE spacecraft, we have examined the intensities of O and Fe in 14 large solar energetic particleevents whose parent activity was in the solar western hemisphere. Sampling the ...
The solar flare of the 14th of July 2000 (L3+C detector results)
(2006-09)
Aims.Several experiments have reported observations on possible correlations between the flux of high energy muons and intense solar flares. If confirmed, these observations would have significant implications for acceleration ...
A multisite photometric campaign on the pre-main-sequence δ Scuti pulsator IP Persei
(2006-04)
We present the results of a photometric multisite campaign on the δ Scuti Pre-Main-Sequence star IP Per. Nine telescopes have been involved in the observations, with a total of about 190 h of observations over 38 nights. ...
LP 400-22, a Very Low Mass and High-Velocity White Dwarf
(2006-03-08)
We report the identification of LP 400-22 (WD 2234+222) as a very low mass and high-velocity white dwarf. The ultraviolet GALEX and optical photometric colors and a spectral line analysis of LP 400-22 show this star to ...
A Statistical Analysis of Wide Binary Evolution
(2006-12)
Post main sequence (MS) mass loss causes orbital separation
amplification in fragile (i.e. common proper motion) binary star
systems. Components typically have separations around -1000 a.u.
Such wide pairs experience ...
