Summary
What do you imagine about the universe? Many people may think of stars or Milky way (our Galaxy) first of all. However, the main target of my research is what is left after the death of a star. A star whose mass is larger than 8 solar mass will end its life with a huge explosion called a supernova. After that its central core will become a compact object such as a neutron star (pulsar) or a black hole, and these objects will shine very brightly and show violent time variability. Moreover, from these phenomena various kinds of messengers other than electromagnetic waves such as neutrinos and high energy particles called cosmic rays will be emitted. We can say that a dead star would be more active and show various activities than a living star. In this talk I will review the research history of compact objects and transient phenomena caused by them.
* Before Dr. Kawanaka’s talk, Dr. Yamamichi (5th batch) will give a small talk on some impressions of his stay in the US.
