We are living in the era of inflating opportunities in the transient science. Rapid development in transient survey and follow-up programs now allows us to apply various observational diagnostics on progenitor evolution toward explosive transients as well as their explosion mechanisms, which had been far impossible a decade ago. The transient zoo keeps quickly expanding with a number of new classes of transients discovered at a high pace, and theoretical models keep not only expanding but being deepened.

In this three-day workshop, we invite researchers mainly from Japan, Asia, and Australia as well as some from Europe, who are actively working on the transient science and related fields. We also call for contributed talks especially aiming at those by researchers in their early career from Japanese institutes. By doing this, we aim at developing stimulating atmosphere for intensive discussion, hopefully leading to various new projects and new ideas in the transient science in the coming decade. We are especially interested in having ample discussion on the nature of type Ia supernovae, i.e., thermonuclear explosions of a white dwarf, but the workshop topics are not limited to this class of objects and cover various types of transients, including the following topics (as is inferred from the list of the invited speakers).


  • Transient survey projects

  • Follow-up observation projects

  • Type Ia supernovae and white dwarfs

  • Core-collapse supernovae and massive stars

  • Gravitational-wave counterparts and multi-messenger astronomy

  • Various types of explosive transient object

  • Supernova remnants

  • Supernova cosmology

  • Host galaxies and environments around transients
