When the primary star in a close binary system evolves into a giant and engulfs its
companion, its core and the companion temporarily orbit each other inside a common …

I review the influence jets and the bubbles they inflate might have on their ambient gas as
they operate through a negative jet feedback mechanism (JFM). I discuss astrophysical …

Planets with short orbital periods (roughly under 10 days) are common around stars like the
Sun,. Stars expand as they evolve and thus we expect their close planetary companions to …

About ten percent of Sun-like (1–2 M⊙) stars will engulf a 1–10 MJ planet as they expand
during the red giant branch (RGB) or asymptotic giant branch (AGB) phase of their evolution …

At least of white dwarfs show atmospheric pollution by metals, sometimes accompanied by
detectable circumstellar dust/gas discs or (in the case of WD 1145+ 017) transiting …

This paper examines the properties of flows around objects embedded within common
envelopes in the simplified context of a" wind tunnel." We establish characteristic …

This paper investigates the recent stellar-merger transient M31LRN 2015 in the Andromeda
galaxy. We analyze published optical photometry and spectroscopy along with a Hubble …

Common envelope evolution is the most important phase in the lives of many significant
classes of binary stars. During a common envelope phase, the stars temporarily share the …

We present hydrodynamic simulations of the common envelope binary interaction between
a giant star and a compact companion carried out with the adaptive mesh refinement code …

We have simulated a common envelope interaction between a 0.88 M⊙, 90 R⊙, red giant
branch star, and a 0.6 M⊙, compact companion with the smoothed particle hydrodynamics …
