DESCRIPTION:Speakers: Shannon Bowes (University of Toronto)\nDespite the t
 raditional model of a Yellow Supergiant as a brief transitional phase in a
  star’s life before the onset of core helium burning\, there is an incre
 asing catalog of supernovae explosions that have had their progenitors ide
 ntified as Yellow Supergiants from pre-explosion imaging. Notably\, these 
 supernovae are both partially-stripped and hydrogen-poor. The widespread i
 nterpretation for these observations is that a binary companion partially 
 strips the supernova progenitor of its stellar envelope\, after which it s
 ubsequently explodes as a Yellow Supergiant\, having the appropriate tempe
 ratures and luminosities for this regime. Still\, no analogs to these part
 ially-stripped Yellow Supergiants have been discovered in Local Group gala
 xies that can be studied in detail prior to their explosion. Theoretical m
 odels predict that certain pulsations should be excited exclusively in par
 tially stripped Yellow Supergiants\, resulting in unique lightcurve morpho
 logy. Therefore\, the variability of Yellow Supergiants can provide unique
  insight into their stellar structure and the presence of a full or partia
 lly-stripped hydrogen envelope. I will describe the ongoing program to cha
 racterize the variability of hundreds of YSGs in the Magellanic Clouds wit
 h the goal of finding potential partially-stripped Yellow Supergiants. In 
 particular\, I will highlight the identification of candidate Yellow Super
 giants to date that have the predicted hallmarks of partially stripping\, 
 and describe on-going follow-up efforts to confirm the nature of this sub-
 population.\n\nhttps://nyx.physics.mcgill.ca/event/587/contributions/3639/
