    • A massive prestellar clump hosting no high-mass cores 
      Sanhueza, Patricio; Jackson, James; Zhang, Qizhou; Guzmán Fernández, Andrés; Lu, Xing; Stephens, Ian W.; Wang, Ke; Tatematsu, Ken'ichi (IOP Publishing, 2017-06-01)
      The infrared dark cloud (IRDC) G028.23-00.19 hosts a massive (1500M(circle dot)), cold (12 K), and 3.6-70 mu m IR dark clump (MM1) that has the potential to form high-mass stars. We observed this prestellar clump candidate ...

      Planck Galactic Cold Clumps (PGCCs) are considered to be the ideal targets to probe the early phases of star formation. We have conducted a survey of 72 young dense cores inside PGCCs in the Orion complex with the Atacama ...
    • Astrochemical Properties of Planck Cold Clumps 
      Tatematsu, Ken'Ichi; Liu, Tie; Ohashi, Satoshi; Sanhueza, Patricio; Nguyen Lu'O'Ng, Quang; Hirota, Tomoya; Liu, Sheng Yuan; Hirano, Naomi; Choi, Minho; Kang, Miju; Thompson, Mark A.; Fuller, Gary; Wu, Yuefang; Li, Di; Di Francesco, James; Kim, Kee Tae; Wang, Ke; Ristorcelli, Isabelle; Juvela, Mika; Shinnaga, Hiroko; Cunningham, María; Saito, Masao; Lee, Jeong-Eun; Tóth, L. Viktor; He, Jinhua; Sakai, Takeshi; Kim, Jungha (IOP Publishing, 2017)
      We observed 13 Planck cold clumps with the James Clerk Maxwell Telescope/SCUBA-2 and with the Nobeyama 45 m radio telescope. The N2H+ distribution obtained with the Nobeyama telescope is quite similar to SCUBA-2 dust ...
    • Eeffect of feedback of massive stars in the fragmentation, distribution, and kinematics of the gas in two ...
