Recollections from my collaboration with Hans Bethe

Hans Bethe visited H. Yukawa at the Yukawa Institute of Kyoto University in 1969 for a period of about six months. During his stay he met with the group of Prof. Hayashi, the leading nuclear astrophysicist in Japan. Many graduate students, including myself, as well as other young astrophysicists were inspired by the discussions with Bethe. I was fortunate to have had an opportunity to collaborate with Bethe on the subject of ``nuclei in neutron star matter.'' In this talk, I shall speak about my memories of Bethe during this period. Although it was for but a short time, the research which was initiated in the collaboration with Hans Bethe developed into a full program involving neutron stars, supernovae, and neutrino astrophysics.
