"Search for young planetary mass objects in star-forming regions"

時間/地點: 2015-12-11 14:00 [S4-1013]

摘要:

Planetary mass objects (PMOs) have mass smaller than 13 Jovian mass which is the lowest mass for deuterium burning. Without sustainable energy production, PMOs are fading out after their birth. To date, only a handful PMOs have been discovered in fields with large area sky surveys such as PS1 and UKIDSS. In contrast of the PMO sample in the field, PMOs in star-forming regions provide chances to understand their formation and early evolution. In addition, young PMOs are good analogues to exoplanets to study their atmospheres without disturbance from host stars. In this talk, I will present our recent results and future developments to search for planetary mass objects in Rho Oph and Taurus star-forming regions.
