The White Dwarfs in AM CVn systems - candidates for SN Ia?
Jan-Erik Solheim, Lev R. Yungelson
Thanks to the rapid increase of observations of Supernovae Ia, we may now claim that the Universe is accelerating. SN Ia are believed to be good standard candles, and after correct…
Double degenerates and progenitors of supernovae type Ia
R. Napiwotzki, L. Yungelson, G. Nelemans +12
We report on systematic radial velocity surveys for white dwarf - white dwarf binaries (double degenerates - DDs) including SPY (ESO Supernovae Ia progenitor survey) recently carri…
Search for double degenerate progenitors of supernovae type Ia with SPY
R. Napiwotzki, H. Drechsel, U. Heber +13
We report on a large survey for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surve…
Fun for Two
S. F. Portegies Zwart, L. R. Yungelson, G. Nelemans
We performed populations synthesis calculations of single stars and binaries and show that binary evolution is extremely important for Galactic astronomy. We review several binary…
Reconstructing the evolution of double helium white dwarfs: envelope loss without spiral-in
Gijs Nelemans, Frank Verbunt, Lev R. Yungelson +1
The unique core-mass - radius relation for giants with degenerate helium cores enables us to reconstruct the evolution of three observed double helium white dwarfs with known masse…
Gamma-ray bursts and density evolution of neutron star binary mergers
Philippe Bagot, Simon F. Portegies Zwart, Lev R. Yungelson
The evolution of the comoving cosmic merger-rate density of neutron star binaries n_c(z) is calculated using a distribution of their merging times provided by population-synthesis…
