[Secretaría de Ciencia y Técnica]

A toda la comunidad,

les recordamos que mañana a las 10:30hs, en el Salón Meridiano, se 
llevará a cabo el Seminario FCAG titulado: *"**Yellow hypergiants: a 
missing piece in the late massive-star evolution"*.**El mismo estará a 
cargo del*Dr.* *Michalis Kourniotis* (Astronomical Institute, Czech 
Academy of Sciences) investigador invitado de la Dra. Lydia Cidale, en 
el marco del Proyecto POEMS. A continuación les dejamos el resumen y los 
datos de conexión para aquellos que no puedan acercarse al Salón Meridiano.

****Resumen: *Yellow hypergiants (YHGs) is a rare class of evolved 
massive stars, which are believed to be in a post-red supergiant phase 
evolving towards hotter temperatures. I will give a review on the 
physics underlying their unstable and eruptive nature, as well as speak 
about observations of the few YHG counterparts in the Local Group. Among 
the findings, our contribution in the YHG studies will be discussed. As 
part of the seminar talk, I will further speak about my study as a 
visiting researcher in the Observatory of La Plata. By exploiting the 
wealth of high-cadence photometric data from TESS, the latter work 
focuses on
extracting the multiperiodic properties of ~50 southern B-supergiants 
with obtained spectroscopy from CASLEO, with the goal of drawing 
correlations between the properties of these stars and their 
pulsational, binarity, and evolutionary status.
