Shocks and Photoionization of the Inner 650 au Jet of the Interacting Binary Star R Aquarii from Multiwavelength Hubble Space Telescope Observations

open access: yesThe Astrophysical Journal, 2023
Astrophysical jets are present in a range of environments, including young stellar objects, X-ray binaries, and active galactic nuclei, but their formation is still not fully understood.

Binary Interaction Dominates the Evolution of Massive Stars [PDF]

open access: yesScience, 2012
Star Partners Stars more massive than eight times the mass of the Sun are rare and short-lived, yet they are fundamentally important because they produce all the heavy elements in the universe, such as iron, silicon, and calcium. Sana et al. (p. 444

Roadmap on the theoretical work of BinaMIcS [PDF]

open access: yes, 2013
We review the different theoretical challenges concerning magnetism in interacting binary or multiple stars that will be studied in the BinaMIcS (Binarity and Magnetic Interactions in various classes of Stars) project during the corresponding ...

Eta Carinae in the Context of the Most Massive Stars [PDF]

open access: yes, 2009
Eta Car, with its historical outbursts, visible ejecta and massive, variable winds, continues to challenge both observers and modelers. In just the past five years over 100 papers have been published on this fascinating object.

How unique is Plaskett's star? A search for organized magnetic fields in short period, interacting or post-interaction massive binary systems [PDF]

open access: yes, 2017
Amongst O-type stars with detected magnetic fields, the fast rotator in the close binary called Plaskett's star shows a variety of unusual properties.

The impact of binary-star yields on the spectra of galaxies [PDF]

open access: yes, 2009
One of the complexities in modelling integrated spectra of stellar populations is the effect of interacting binary stars besides Type Ia supernovae (SNeIa).

Dynamically Forming Extremely Low-mass White Dwarf Binaries in Wide Orbits

open access: yesThe Astrophysical Journal, 2023
The detection of a 0.2 M _⊙ extremely low-mass white dwarf (EW) in a wide orbit ( P _orb ≈ 450 days) with a 1.1 M _⊙ main-sequence companion, KIC 8145411, challenges our current understanding of how EWs form. The traditional channel for EW formation, via

The origin of single radio pulsars

open access: yes, 1999
By comparing relative rates of supernovae versus formation rates of single radio pulsars, recycled pulsars, binary pulsars and X-ray binaries we put strong limits on the progenitors of radio pulsars and on the requirement of an asymmetry in the supernova.

Binary Interactions in Star Clusters [PDF]

open access: yesSymposium - International Astronomical Union, 1988
Over the past decade, a very considerable amount of effort in stellar dynamics has gone into the study of interactions between binary systems and other stars. The asymptotic analytic results obtained by Heggie (1975) for binary-single star encounters have been largely confirmed and extended by later numerical experiments (Hills 1975, Hut and Bahcall ...
