</p>
<p>les recordamos que mañana a las 10:30hs, en el Salón Meridiano,
se llevará a cabo el Seminario FCAG titulado: <b>"</b><b>Yellow
hypergiants: a missing piece in the late massive-star evolution"</b>.<b>
</b>El mismo estará a cargo del<b> Dr.</b> <b>Michalis
Kourniotis</b> (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

</b><b></b><b>Resumen: </b>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 <br>
</div>
<div> 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.<br>
