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 …

It is 30 years since the characteristic signatures of interaction with circumstellar material
(CSM) were first observed in a core-collapse supernova. Since then, CSM interaction has …

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 …

Supernova (SN) 2016bdu is an unusual transient resembling SN 2009ip. SN 2009ip-like
events are characterized by a long-lasting phase of erratic variability that ends with two …

The historical light curve of the 19th century 'Great Eruption'of η Carinae provides a striking
record of the violent instabilities encountered by massive stars. In this paper, we report and …

We propose a common-envelope jets supernova scenario for the enigmatic supernova
iPTF14hls where a neutron star that spirals-in inside the envelope of a massive giant star …

ABSTRACT I suggest a spiral-in process in which a stellar companion grazes the envelope
of a giant star while both the orbital separation and the giant radius shrink simultaneously …

We discuss the events that led to the giant eruption of Eta Carinae, and find that the mid-
nineteenth century (in 1838–1843) giant mass-loss outburst has the characteristics of being …

ABSTRACT Type Ibn supernovae (SNe Ibn) are intriguing stellar explosions whose spectra
exhibit narrow helium lines with little hydrogen. They trace the presence of circumstellar …

We present two-dimensional (2D) radiative transfer modelling of the Eta Carinae binary
system accounting for the presence of a wind–wind collision (WWC) cavity carved in the …
