Oral Presentation

SMA follow-up observations of Planck cold clumps

Author(s): Tie Liu (KASI); on behalf of the TOP-SCOPE project members

Presenter: Tie Liu (KASI)

The low dust temperature (<14 K) of Planck Galactic Cold Clumps (PGCCs) makes them likely to be pre-stellar objects or at the very initial stage of protostellar collapse. "TOP-SCOPE" are joint survey programs targeting at Planck Cold Clumps. "TOP", standing for "TRAO Observations of Planck cold clumps", aims at an unbiased CO/13CO survey of 2000 Planck Galactic Cold Clumps with the Taeduk Radio Astronomy Observatory 14-meter telesope. "SCOPE", standing for "SCUBA-2 Continuum Observations of Pre-protostellar Evolution", is a legacy survey using SCUBA-2 onboard of the James Clerk Maxwell Telescope (JCMT) at East Asia Observatory (EAO) to survey 1000 Planck galactic cold clumps at 850 micron. We are also actively developing follow-up observations with other ground-based telescopes (NRO 45-m, Effelsberg 100-m, IRAM 30-m. SMT, KVN, SMA, ALMA). From these surveys, we have identified hundreds of very young dense cores, which could be interesting candidates for SMA follow-ups. In this talk, I will firstly introduce the Discovery of an Extremely Young Class 0 Protostellar Object and a Proto-brown Dwarf Candidate in the Bright-rimmed Clump PGCC G192.32-11.88 with both the JCMT and the SMA. Then I will discuss our future plans to use the SMA to follow-up observe the SCUBA-2 cores detected in "SCOPE".
