Mass loss is a key process in the evolution of massive stars, and must be understood
quantitatively if it is to be successfully included in broader astrophysical applications such as …

Luminous blue variables (LBVs) had long been considered massive stars in transition to the
Wolf–Rayet (WR) phase, so their identification as progenitors of some peculiar supernovae …

Based on their relatively isolated environments, we argue that luminous blue variables
(LBVs) must be primarily the product of binary evolution, challenging the traditional single …

We investigate the fundamental properties of core-collapse supernova (SN) progenitors from
single stars at solar metallicity. For this purpose, we combine Geneva stellar evolutionary …

Context. It has been proposed that the envelopes of luminous stars may be subject to
substantial radius inflation. The peculiar structure of such inflated envelopes, with an almost …

In this paper, we report the results of spectroscopic and photometric observations of the
candidate evolved massive star MN48 disclosed via detection of a mid-infrared circular shell …

We present a detailed spectroscopic analysis of the luminous blue variable (LBV) AG
Carinae (AG Car) during the last two visual minimum phases of its S-Dor cycle (1985–1990 …

The interaction between supernova ejecta and circumstellar matter, arising from previous
episodes of mass loss, provides us with a means of constraining the progenitors of …

Luminous blue variables (LBVs) are hot, very luminous massive stars displaying large quasi-
periodic variations in brightness, radius, and photospheric temperature on timescales of …

The classic example of a Type IIb supernova is SN 1993J, which had a cool extended
progenitor surrounded by a dense wind. There is evidence for another category of Type IIb …
