SUMMARY:Exploring Axion-like Particles with Nearby Supernovae\, Networ
 k in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar\
 , Kanji Mori \, Fukuoka University\, Japan
DESCRIPTION:Axion-like particles (ALPs) are hypothetical pseudo-Nambu-
 Goldstone bosons which are a candidate of dark matter. Since they are 
 thought to couple with photons\, ALPs can be produced in hot astrophys
 ical plasma. Once produced\, ALPs decay into photons which may be obse
 rvable with gamma-ray telescopes. I calculated the ALP emission from a
  thermonuclear (i.e. type Ia) supernova and a massive star in the fina
 l stage of stellar evolution. It is shown that gamma-rays that origina
 te from ALPs can be a target of next-generation gamma-ray telescopes a
 nd provide an independent constraint on ALP parameters. Also\, ALPs ma
 y affect energy transfer in core-collapse supernovae. I will mention a
  preliminary result on supernova explosion aided by heavy ALPs.
