Vlt/Pionier Imaging Of Red Supergiant Stars
, 2018 PIONIER (Precision Integrated-Optics Near-infrared Imaging ExpeRiment) was the first 4-telescope instrument installed at the Very Large Telescope Interferometer (VLTI) in 2010. Benefiting from the multiple interferometric configurations available at the Cerro Paranal observatory, it can efficiently image stellar surfaces. With their large linear sizes,

Betelgeuse, the Prototypical Red Supergiant
GalaxiesThe behavior of the bright red supergiant, Betelgeuse, is described with results principally from the past 6 years. The review includes imaging, photometry, and spectroscopy to record the Great Dimming of 2019–2020.

Atmosphere tomography of red supergiant stars
EAS Publications Series, 2013 3-D simulations suggest that the atmospheres of red super-giants are subject to large-amplitude convective motions, which are suspected to generate supersonic motions and shocks. We perform tomography of supergiant-star atmospheres, on temporal series of high-resolution spectra and on 3-D hydrodynamical synthetic spectra.

Stellar Evolution Through the Red Supergiant Phase
GalaxiesMassive stars less massive than ∼30 M⊙ evolve into a red supergiant after the main sequence. Given a standard IMF, this means about 80% of all single massive stars will experience this phase.

Detection of a Red Supergiant Progenitor Star of a Type II-Plateau Supernova
Science, 2004 We present the discovery of a red supergiant star that exploded as supernova 2003gd in the nearby spiral galaxy M74. The Hubble Space Telescope (HST) and the Gemini Telescope imaged this galaxy 6 to 9 months before the supernova explosion, and subsequent HST images confirm the positional coincidence of the supernova with a single resolved ...

A Bias-corrected Luminosity Function for Red Supergiant Supernova Progenitor Stars
The Astrophysical Journal LettersThe apparent tension between the luminosity functions of red supergiant (RSG) stars and of RSG progenitors of Type II supernovae (SNe) is often referred to as the RSG problem and it motivated some to suggest that many RSGs end their life without an SN ...

Red supergiants in star-forming galaxies [PDF]
Symposium - International Astronomical Union, 1999 We present some results on the burst properties in star forming galaxies, using near infrared stellar features typical of red supergiants and Brackett nebular lines which trace the presence of luminous H II regions.

Lithium Detection in Red Supergiant Stars of the Perseus Complex
The Astrophysical Journal, 2022 Abstract We present the first systematic study of lithium abundance in a chemically homogeneous sample of 27 red supergiants (RSGs) in the young Perseus complex. For these stars, accurate stellar parameters and detailed chemical abundances of iron and iron peak, CNO, alpha, light, and neutron capture elements have already been obtained ...
