Probing the Innermost Region of the V883 Ori Disk Using ALMA Band 1 Methanol Line Observations
Yoshihide Yamato, Shota Notsu, Rui Zhuang +2
The study uses ALMA Band 1 observations to detect methanol emission lines in the protoplanetary disk around the FU‑Ori star V883 Ori, revealing warm gaseous methanol in the innermo…
GREX-PLUS Science Book v2
PLUS Science Team, Shunsuke Baba, Sirio Belli +52
GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…
Compact Hydrogen Sulfide Emission Indicates Sulfur-bearing Ice Sublimation in the Inner Disk of HD 163296
Yoshihide Yamato, Yuri Aikawa, Kenji Furuya +8
The sulfur chemistry in protoplanetary disks directly affects the composition and potential habitability of nascent planets, but its volatile inventory remains highly uncertain. He…
ALMA Band 7 Observations of Water Lines in the Protoplanetary Disk of V883 Ori
Hiroto Nakasone, Shota Notsu, Tomohiro C. Yoshida +8
The FU Orionis star V883 Ori provides a unique opportunity to probe the water snowline in a protoplanetary disk. During an accretion burst, the enhanced stellar luminosity heats th…
The chemical diversity of giant-planet nurseries as revealed by ALMA
Alice S. Booth, Jenny Calahan, Milou Temmink +9
With the giant exoplanet occurrence rate peaking around stars of 1.5-2 solar masses, there is strong motivation to characterize the disks that set their formation conditions. Obser…
Ice sublimation in the dynamic HD 100453 disk reveals a rich reservoir of inherited complex organics
Alice S. Booth, Lisa Wölfer, Milou Temmink +7
Protoplanetary disks around luminous young A-type stars are prime observational laboratories to determine the abundances of complex organic molecules (COMs) present during planet f…
