The VLT-FLAMES survey of massive stars. NGC2004#115: A triple system hosting a possible short period B+BH binary
D. J. Lennon, P. L. Dufton, J. I. Villaseñor +5
The star NGC2004#115 in the LMC, originally classified as an (SB1) Be spectroscopic binary, bears some morphological resemblance to the Galactic systems LB-1 and HR 6819, both of w…
Helium ignition in rotating magnetized CO white dwarfs leading to fast and faint rather than classical type Ia supernovae
P. Neunteufel, S. -C. Yoon, N. Langer
Based mostly on stellar models which do not include rotation, CO white dwarfs which accrete helium at rates of about have been put forwa…
B fields in OB stars (BOB): The magnetic triple stellar system HD 164492C in the Trifid nebula
J. F. Gonzalez, S. Hubrig, N. Przybilla +15
HD 164492C is a spectroscopic triple stellar system that has been recently detected to possess a strong magnetic field. We have obtained high-resolution spectroscopic and spectropo…
Imprints of the ejecta-companion interaction in Type Ia supernovae: main sequence, subgiant, and red giant companions
P. Boehner, T. Plewa, N. Langer
We study supernova ejecta-companion interactions in a sample of realistic semidetached binary systems representative of Type Ia supernova progenitor binaries in a single-degenerate…
Asteroseismic test of rotational mixing in low-mass white dwarfs
A. G. Istrate, G. Fontaine, A. Gianninas +4
We exploit the recent discovery of pulsations in mixed-atmosphere (He/H), extremely low-mass white dwarf precursors (ELM proto-WDs) to test the proposition that rotational mixing i…
Rotating Stars and the Formation of Bipolar Planetary Nebulae II: Tidal Spin-up
G. Garcia-Segura, E. Villaver, A. Manchado +2
We present new binary stellar evolution models that include the effects of tidal forces, rotation, and magnetic torques with the goal of testing Planetary Nebulae (PNe) shaping via…
