The mass distribution of clumpy accretion onto the nearby young star TW Hya
Tao Ji, Javier Serna, Gregory J. Herczeg +12
The proliferation of high time-resolution and decades-long monitoring of classical T Tauri stars provides a vast opportunity to test the variability of the star-disk connections. H…
X-ray emission of F-type stars and its analogy with G-type stars
Takuma Shimura, Ikuyuki Mitsuishi, Masanobu Kunitomo +3
We conducted a systematic spectral study for single F-type main-sequence (MS) stars without significant X-ray outbursts to investigate X-ray spectral properties such as temperature…
A Necessary Condition for the Submergence of Proto-Neutron Star Magnetic Fields by Supernova Fallback
Akihiro Inoue, Shinsuke Takasao, Kazumi Kashiyama +2
Central compact objects (CCOs) are a subclass of neutron stars with a dipole magnetic field strength considerably weaker than those of radio pulsars and magnetars. One possible exp…
Model of X-ray and extreme-UV emission from magnetically heated atmospheres in classical T Tauri stars: Case study of TW Hya
Munehito Shoda, Riouhei Nakatani, Shinsuke Takasao
Photoevaporation caused by X-rays and ultraviolet radiation from the central star has attracted attention as a key process driving the dispersal of protoplanetary discs. Although n…
Connecting a Magnetized Disk to a Convective Low-mass Protostar: A Global Three-dimensional Model of Boundary Layer Accretion
Shinsuke Takasao, Takashi Hosokawa, Kengo Tomida +1
In the early stages of star formation, boundary layer accretion, where protostars accrete material from disks extending down to their surfaces, plays a crucial role. Understanding…
Evidence for Variable Accretion onto PDS 70 c and Implications for Protoplanet Detections
Yifan Zhou, Brendan P. Bowler, Aniket Sanghi +14
Understanding the processes of planet formation and accretion in young systems is essential to unraveling the initial conditions of planetary systems. The PDS 70 system, which host…
NuSTAR detection of a hot stellar superflare with a temperature of 95 MK in hard X-rays
Tomohiro Hakamata, Hironori Matsumoto, Hirokazu Odaka +1
A search of the hard X-ray archive data of NuSTAR found a transient source, NuSTAR J230059+5857.4, during an observation of 1E 2259+586 on 2013 April 25. A multi-wavelength analysi…
