The origin of single radio pulsars
, 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.

Quantitative spectroscopy of close binary stars [PDF]
, 2011 The method of spectral disentangling has now created the opportunity for studying the chemical composition in previously inaccessible components of binary and multiple stars.

Interacting Binary White Dwarf Stars [PDF]
Symposium - International Astronomical Union, 1992 This group of stars consists of 4 systems, also called helium cataclysmics. Three of them show photometric variations and have been studied by the Whole Earth Telescope (WET), which have revealed multiperiodic light curves showing the signature of g-mode non-radial pulsations on the accreting star.

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

Binary Interactions in Star Clusters [PDF]
Symposium - 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 ...

A dusty pinwheel nebula around the massive star WR 104 [PDF]
, 1999 Wolf-Rayet (WR) stars are luminous massive blue stars thought to be immediate precursors to the supernova terminating their brief lives. The existence of dust shells around such stars has been enigmatic since their discovery some 30 years ago; the ...

Be Stars as Interacting Binaries [PDF]
Symposium - International Astronomical Union, 1982 At the last IAU Symposium on Be stars held in Bass River, MA in 1975, several of us (including P. Harmanec, M. Plavec, R.S. Polidan, and myself) suggested that Be stars are mass transfer binaries and represent the higher mass counterparts to the familiar Algol systems.

Multiple Tidal Disruptions as an Indicator of Binary Super-Massive Black Hole Systems [PDF]
, 2010 We find that the majority of systems hosting multiple tidal disruptions are likely to contain hard binary SMBH systems, and also show that the rates of these repeated events are high enough to be detected by LSST over its lifetime.

Interacting Binaries as Be Stars [PDF]
International Astronomical Union Colloquium, 1987 AbstractSemidetached close binary stars of the Algol type often have primary components of spectral type A0 or earlier and display emission at Hα (sometimes also at higher Balmer lines). They are therefore Be stars. Many binaries of this type are not eclipsing and must look like “ordinary” Be stars.

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