SPH Methods in the Modelling of Compact Objects
- Physics
- 2014
We review the current status of compact object simulations that are based on the smooth particle hydrodynamics (SPH) method. The first main part of this review is dedicated to SPH as a numerical…
Bondi-Hoyle-Lyttleton Accretion in a Reactive Medium: Detonation Ignition and a Mechanism for SNe Ia
- Physics
- 2021
Detonation initiation in a reactive medium can be achieved by an externally created shock wave. Supersonic flow onto a gravitating center, known as Bondi-Hoyle-Lyttleton (BHL) accretion, is a natural…
Post asymptotic giant branch and central stars of planetary nebulae in the Galactic halo
- Physics
- 2012
Post asymptotic giant branch (post-AGB) stars, central stars of planetary nebulae (CSPNe) and planetary nebulae (PNe) are important phases of stellar evolution as the material they feedback is the…
PRELUDE TO A DOUBLE DEGENERATE MERGER: THE ONSET OF MASS TRANSFER AND ITS IMPACT ON GRAVITATIONAL WAVES AND SURFACE DETONATIONS
- Physics
- 2011
We present the results of a systematic numerical study of the onset of mass transfer in double degenerate binary systems and its impact on the subsequent evolution. All investigated systems belong to…
Gaia photometry for white dwarfs
- Physics, Geology
- 2014
Context. White dwarfs can be used to study the structure and evolution of the Galaxy by analysing their luminosity function and initial mass function. Among them, the very cool white dwarfs provide…
Possible white dwarf progenitors of Type Ia supernovae
- PhysicsMonthly Notices of the Royal Astronomical Society
- 2018
We examine catalogs of white dwarfs (WDs) and find that there are sufficient number of massive WDs, M_WD > 1.35Mo, that might potentially explode as type Ia supernovae (SNe Ia) in the frame of the…
The structure and fate of white dwarf merger remnants
- Physics
- 2014
We present a large parameter study where we investigate the structure of white dwarf (WD) merger remnants after the dynamical phase. A wide range of WD masses and compositions are explored, and we…
Revisiting constraints on asymmetric dark matter from collapse in white dwarf stars
- PhysicsPhysical Review D
- 2022
The runaway collapse phase of a small dark matter cluster inside a white dwarf star encompasses a reversible stage, where heat can be transferred back and forth between nuclear and dark matter.…
Exotic compact objects: The dark white dwarf
- Physics, GeologyPhysical Review D
- 2022
Several dark matter models allow for the intriguing possibility of exotic compact object formation. These objects might have unique characteristics that set them apart from their baryonic…
On the impact of non-local gravity on compact stars
- Physics, Geology
- 2021
We study the impact of non-local modifications of General Relativity on stellar structure. In particular, assuming an analytic distortion function, we made use of remnant stars to put qualitative…

Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Milky Way. The…
A NEW LOOK AT THE LOCAL WHITE DWARF POPULATION
- Physics, Geology
- 2008
We have conducted a detailed new survey of the local population of white dwarfs lying within 20 pc of the Sun. A new revised catalog of local white dwarfs containing 122 entries (126 individual…
The MACHO Project: Microlensing Results from 5.7 Years of Large Magellanic Cloud Observations
- Physics
- 2000
We report on our search for microlensing toward the Large Magellanic Cloud (LMC). Analysis of 5.7 yr of photometry on 11.9 million stars in the LMC reveals 13-17 microlensing events. A detailed…

Direct Detection of Galactic Halo Dark Matter
- Physics, GeologyScience
- 2001
A survey to find faint, cool white dwarfs with large space velocities, indicative of their membership in the galaxy's spherical halo component reveals a substantial, directly observed population of oldwhite dwarfs, too faint to be seen in previous surveys, and represents a direct detection of galactic halo dark matter.
