<div><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>
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>
