Asymmetric, variable H line profile in planetary mass object SR 12 c
Jun Hashimoto, Yuhiko Aoyama, Michihiro Takami +1
Young, forming planetary-mass objects often exhibit clear signatures of ongoing mass accretion and are thought to accrete material through processes analogous to those operating in…
A Hybrid Origin for the Multiple Ring-Gap Structures in the Large Protoplanetary Disk V1094 Sco: A Low-Mass Planet and Secular Gravitational Instability
Masayuki Yamaguchi, Masahiro N. Machida, Ryosuke T. Tominaga +7
High spatial resolution observations reveal that some protoplanetary disks host multiple ring-gap pairs at large stellocentric radii, yet their physical origin remains unsettled. W…
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…
The Relationship between Accretion and Ionised Ejection among Young Stellar Objects in the Coronet Cluster
Arpan Ghosh, Roberto Galván-Madrid, Johanan RamÃrez-Arellano +7
We present results from a coordinated, multi-epoch near-infrared and centimeter radio survey of young stellar objects (YSOs) in the Coronet, aimed at probing the connection between…
Morphological and Kinematical Diagnostic of FU Orionis-type Outburst Mechanisms
Jinshi Sai, Eduard I. Vorobyov, Alexandr Skliarevskii +1
We investigated the possibility of determining the mechanism of the FU Orionis-type outburst based on molecular line observations of protoplanetary disks with synthetic observation…
Peculiar Disk Substructures Associated with the Young Eruptive Star EX Lupi
Masayuki Yamaguchi, Hauyu Baobab Liu, Michihiro Takami +1
Young eruptive stars such as EXors undergo dramatic accretion outbursts characterized by sudden optical brightenings, yet the underlying physical mechanism remains uncertain. We pr…
