The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
Photometric study of three ultrashort-period contact binaries
L. Liu, S. -B., E. Fernandez Lajus +3
We carried out high-precision photometric observations of three eclipsing ultrashortperiod contact binaries (USPCBs). Theoretical models were fitted to the light-curves by means of…
A new mechanism of long-term period variations for W UMa-type contact binaries
Liang Liu, Shengbang Qian, Xiao Xiong
W UMa-type contact binaries belong to close binary systems whose components exactly overflow their Roche lobes and share a common convective envelope (CCE). In the last twenty year…
Followup Observations of SDSS and CRTS Candidate Cataclysmic Variables II
Paula Szkody, Mark E. Everett, Zhibin Dai +1
Spectra of 38 candidate or known cataclysmic variables are presented. Most are candidate dwarf novae or systems containing possible highly magnetic white dwarfs, while a few (KR Au…
Isotopic ratios in outbursting comet C/2015 ER61
Bin Yang, Damien Hutsemekers, Yoshiharu Shinnaka +7
Isotopic ratios in comets are critical to understanding the origin of cometary material and the physical and chemical conditions in the early solar nebula. Comet C/2015 ER61 (PANST…
