Pulsation Driving Forces in Less-Massive Supergiants [PDF]

, 2010
application/pdfWe demonstrate at first that the blue edge of the fundamental mode of luminous less-massive supergiant models is shifted blue-wards with increasing luminosities (we call it the blue edge anomaly).

Constraining the z ∼ 1 Initial Mass Function with HST and JWST Lensed Stars in MACS J0416.1−2403

The Astrophysical Journal
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date the IMF is constrained only to local galaxies.

On the lithium abundance in F-, G-supergiants and its possible correlation with rotation

, 2005
From the abundance study of a great quantity of luminosity type I and II supergiants we identified five first-crossing objects, which are rare massive stars evolving from their progenitors, main-sequence B stars, to red supergiants for the first time ...

Is Betelgeuse Really Rotating? Synthetic ALMA Observations of Large-scale Convection in 3D Simulations of Red Supergiants

The Astrophysical Journal Letters
The evolved stages of massive stars are poorly understood, but invaluable constraints can be derived from spatially resolved observations of nearby red supergiants, such as Betelgeuse.

MUSE 3D spectroscopy of BA-type supergiants in NGC 300

We present the results obtained using spectroscopic data taken with the intermediateresolution Multi Unit Spectroscopic Explorer (MUSE) of B and A-type supergiants and bright giants in the Sculptor Group galaxy NGC 300.
