Measuring the Mass–Radius Relation of White Dwarfs Using Wide Binaries

The Astrophysical Journal
Measuring the mass–radius relation of individual white dwarfs is an empirically challenging task that has been performed for only a few dozen stars. We measure the white dwarf mass–radius relation using the gravitational redshifts and radii of 135 white ...

Matching your way to Success: The Influence of Motivational Frame Matching on Interaction Outcomes and Reciprocal Matching

European Journal of Social Psychology, EarlyView.
ABSTRACT Theories of interpersonal sensemaking postulate that positive interactions emerge in interactions where speakers match on motivational frames. Across three experiments (N = 1609) using a hypothetical simulation framework, we provide the first evidence of a causal link between motivational frame matching and positive interaction outcomes in ...

Hunting for Polluted White Dwarfs and Other Treasures with Gaia XP Spectra and Unsupervised Machine Learning

The Astrophysical Journal
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are often limited by brightness constraints, and WDs tend to be very faint, making ...

Illness Perceptions in Psychiatric Disorders: Assessing Differences and Associations With Symptom Severity

European Eating Disorders Review, EarlyView.
ABSTRACT Objectives This study investigated the influence of illness perceptions (IPs) on clinical severity across Major Depressive Disorder (MDD), Anorexia Nervosa (AN), Generalised Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), and Panic Disorder (PD), and compared the IPs across these conditions.

Evolution of Cataclysmic Variables with Binary-driven Mass Loss during Nova Eruptions

The Astrophysical Journal
The discrepancies between observations and theoretical predictions of cataclysmic variables (CVs) suggest that there exists unknown angular-momentum-loss mechanism(s) besides magnetic braking and gravitational radiation.

Simulating Gaia performances on white dwarfs

, 2005
One of the most promising space missions of ESA is the astrometric satellite Gaia, which will provide very precise astrometry and multicolour photometry, for all 1.3 billion objects to V~20, and radial velocities with accuracies of a few km/s for most ...

Lessons for asteroseismology from white dwarf stars [PDF]

Journal of Astrophysics and Astronomy, 2005
The interpretation of pulsation data for Sun-like stars is currently facing challenges quite similar to those faced by white dwarf modelers ten years ago. The observational requirements for uninterrupted long-term monitoring are beginning to be satisfied by successful multi-site campaigns and dedicated satellite missions.

Predicting Major Depression Among Diverse Online Gamers: The Role of Internet Addiction and Spirituality

Journal of Addictions &Offender Counseling, EarlyView.
ABSTRACT This study analyzed whether religious or spiritual affiliation and therapy enrollment protect against symptoms meeting Major Depressive Disorder criteria beyond demographic, Internet addiction, and described therapy enrollment. Findings illustrated one risk factor and one protective factor associated with experiencing symptoms that meet Major ...
