astro-ph.EP2021

13C isotopic ratios of HC3​N on Titan measured with ALMA

Takahiro Iino, Kotomi Taniguchi, Hideo Sagawa +1

We present the first determination of the abundance ratios of 13C substitutions of cyanoacetylene (HC3​N), [H13CCCN]:[HC13CCN]:[HCC13CN] in Titan's atmosphe…

astro-ph.EP2020

A stringent upper limit of the PH3​ abundance at the cloud top of Venus

T. Encrenaz, T. K. Greathouse, E. Marcq +7

Following the announcement of the detection of phosphine (PH3​) in the cloud deck of Venus at millimeter wavelengths, we have searched for other possible signatures of this molec…

astro-ph.EP2020

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…

14N/15N isotopic ratio in CH3​CN 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…
