BURYING A BINARY: DYNAMICAL MASS LOSS AND A CONTINUOUS OPTICALLY THICK OUTFLOW EXPLAIN THE CANDIDATE STELLAR MERGER V1309 SCORPII [PDF]
, 2013 V1309 Sco was proposed to be a stellar merger and a common envelope transient based on the pre-outburst light curve of a contact eclipsing binary with a rapidly decaying orbital period.

Dance to Demise—How Massive Stars May Form Dense Circumstellar Shells before Explosion
The Astrophysical JournalWe investigate the evolution of red supergiant (RSG) progenitors of core-collapse supernovae (SNe) with initial masses between 12 and 20 M _⊙ , focusing on the effects of enhanced mass loss due to pulsation-driven instabilities in their envelopes and ...

The Cepheid mass discrepancy and pulsation-driven mass loss
, 2011 Context. A longstanding challenge for understanding classical Cepheids is the Cepheid mass discrepancy, where theoretical mass estimates using stellar evolution and stellar pulsation calculations have been found to differ by approximately 10 - 20%. Aims.

Searching for Stellar-feedback-driven Outflow Signatures: A Deep Dive into NGC 3741
The Astrophysical JournalStellar feedback drives winds and outflows critical to the baryon cycles of low-mass galaxies whose shallow gravitational potential wells make them particularly susceptible to mass and metal loss through outflows. However, spatially resolved observations

Continuum driven winds from super-Eddington stars. A tale of two limits
, 2007 Continuum driving is an effective method to drive a strong stellar wind. It is governed by two limits: the Eddington limit and the photon-tiring limit. A star must exceed the effective Eddington limit for continuum driving to overcome the stellar gravity.

Implications of the metallicity dependence of Wolf-Rayet winds
, 2006 Aims: Recent theoretical predictions for the winds of Wolf-Rayet stars indicate that their mass-loss rates scale with the initial stellar metallicity in the local Universe.We aim to investigate how this predicted dependence affects the models of Wolf ...

The Great Escape II: Exoplanet Ejection from Dying Multiple Star Systems
, 2012 Extrasolar planets and belts of debris orbiting post-main-sequence single stars may become unbound as the evolving star loses mass. In multiple star systems, the presence or co-evolution of the additional stars can significantly complicate the prospects ...

Testing the Rossby Paradigm: Weakened Magnetic Braking in Early K-type Stars
The Astrophysical JournalThere is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds. An essential ingredient for the operation of a large-scale dynamo is the

Mass loss and supernova progenitors
, 2007 We first discuss the mass range of type IIP SN progenitors and how the upper and lower limits impose interesting constraints on stellar evolution. Then we discuss the possible implications of two SNe, 2002ap and 2006jc, for Wolf-Rayet star mass-loss ...
