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

*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.
