The Isotopic Links from Planet Forming Regions to the Solar System

H. Nomura, K. Furuya, M. A. Cordiner +7

Isotopic ratios provide a powerful tool for understanding the origins of materials, including the volatile and refractory matter within solar system bodies. Recent high sensitivity…

C isotopic ratios of HCN on Titan measured with ALMA

Takahiro Iino, Kotomi Taniguchi, Hideo Sagawa +1

We present the first determination of the abundance ratios of C substitutions of cyanoacetylene (HCN), [HCCCN]:[HCCCN]:[HCCCN] in Titan's atmosphe…

HCN =4-3, HNC =1-0, =1-0, and =10-9 Maps of Galactic Center Region II.: Physical Properties of Dense Gas Clumps and Probability of Star Formation

Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai +2

We report a statistical analysis exploring the origin of the overall low star formation efficiency (SFE) of the Galactic central molecular zone (CMZ) and the SFE diversity among th…

A belt-like distribution of gaseous hydrogen cyanide on Neptune's equatorial stratosphere detected by ALMA

Takahiro Iino, Hideo Sagawa, Takashi Tsukagoshi +1

We present a spatially resolved map of integrated-intensity and abundance of Neptune's stratospheric hydrogen cyanide (HCN). The analyzed data were obtained from the archived 2016…

N/N isotopic ratio in CHCN of Titan's atmosphere measured with ALMA

Takahiro Iino, Hideo Sagawa, Takashi Tsukagoshi

Each of the nitriles present in the atmosphere of Titan can be expected to exhibit different \ce{^{14}N/^{15}N} values depending on their production processes, primarily because of…

HCN =4-3, HNC =1-0, =1-0, and =10-9 Maps of Galactic Center Region I: Spatially-Resolved Measurements of Physical Conditions and Chemical Composition

Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai +2

This {\it supplement} paper presents the maps of HCN =4-3, HNC =1-0, =1-0, and HCN =10-9 for the Galactic central molecular zone (CMZ), which ha…
