Implication of Formation Mechanisms of HC5N in TMC-1 as Studied by 13C Isotopic Fractionation
Kotomi Taniguchi, Hiroyuki Ozeki, Masao Saito +5
We observed the J = 9-8 and 16-15 rotational transitions of the normal species and five 13C isotopologues of HC5N to study its formation mechanisms toward the cyanopolyyne peak in…
A multi-wavelength analysis for interferometric (sub-)mm observations of protoplanetary disks: radial constraints on the dust properties and the disk structure
M. Tazzari, L. Testi, B. Ercolano +20
Theoretical models of grain growth predict dust properties to change as a function of protoplanetary disk radius, mass, age and other physical conditions. We lay down the methodolo…
Spatially-resolved Radio-to-Far-infrared SED of the Luminous Merger Remnant NGC 1614 with ALMA and VLA
Toshiki Saito, Daisuke Iono, Cong K. Xu +9
We present the results of Atacama Large Millimeter/Submillimeter Array (ALMA) 108, 233, 352, and 691 GHz continuum observations and Very Large Array (VLA) 4.81 and 8.36 GHz observa…
Two-level hierarchical fragmentation in the Orion Molecular Cloud 1 northern filament
P. S. Teixeira, S. Takahashi, L. A. Zapata +1
[Abridged] We have recently reported on the collapse and fragmentation properties of the northernmost part of this structure, located ~2.4pc north of Orion KL -- the Orion Molecula…
Submillimeter-HCN Diagram for an Energy Diagnostics in the Centers of Galaxies
Takuma Izumi, Kotaro Kohno, Susanne Aalto +16
Compiling data from literature and the ALMA archive, we show enhanced HCN(4-3)/HCO(4-3) and/or HCN(4-3)/CS(7-6) integrated intensity ratios in circumnuclear molecular gas aroun…
A submillimeter search for pre- and proto-brown dwarfs in Chamaeleon II
I. de Gregorio-Monsalvo, D. Barrado, H. Bouy +7
Context. Chamaeleon II molecular cloud is an active star forming region that offers an excellent opportunity for studying the formation of brown dwarfs in the southern hemisphere.…
