Kinematically Resolving the Fe K Complex in Her X-1: The Accretion Disk and Ionized Wind Across X-ray Eclipses
Koh Sakamoto, Teruaki Enoto, Peter Kosec +8
We present XRISM/Resolve spectroscopy of Her X-1 across three X-ray eclipses observed in September 2024, resolving its iron K complex through the ingress, mid-eclipse, and egress p…
XRISM/Resolve observations of Hercules X-1: a pulsating, highly broadened Fe K emission line from the neutron star accretion column
Peter Kosec, Laura Brenneman, Erin Kara +11
The study of X-ray pulsar accretion columns helps us characterize accretion physics in this extreme regime of strong gravity and strong magnetic fields. Previous observations of th…
The Supernova Remnant G284.31.8 and Its Relation to the Gamma-ray Binary 1FGL J1018.65856
Natsuki Terano, Takaaki Tanaka, Hiromasa Suzuki +6
G284.31.8 is a supernova remnant with a radio shell and thermal X-ray emission. Located near its center is the gamma-ray binary 1FGL J1018.65856, although the physical associ…
XRISM/Resolve observations of Hercules X-1: vertical structure and kinematics of the disk wind
Peter Kosec, Laura Brenneman, Erin Kara +11
X-ray binary accretion disk winds can carry away a significant fraction of the matter transferred from the companion and hence strongly affect the accretion flow and the long-term…
Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations
XRISM Collaboration
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…
Evidence for Type Ib/c origin of the supernova remnant G292.0+1.8
Takuto Narita, Hiroyuki Uchida, Jacco Vink +6
Circumstellar material (CSM) produced by mass loss from massive stars () through strong stellar winds or binary stripping provides rich information for underst…
Progenitor Constraint Incorporating Shell Merger: The Case of Supernova Remnant G359.0-0.9
Kai Matsunaga, Hiroyuki Uchida, Rei Enokiya +5
It is generally hard to put robust constraints on progenitor masses of supernovae (SNe) and remnants (SNRs) observationally, while they offer tantalizing clues to understanding exp…
Destratification in the Progenitor Interior of the Mg-rich Supernova Remnant N49B
Toshiki Sato, Kai Matsunaga, Ryo Sawada +6
Simulations of pre-supernova evolution suggest that some intense shell burning can be so active that, in extreme cases, it can merge with the outer shell, changing the initial cond…
Rapid spin changes around a magnetar fast radio burst
Chin-Ping Hu, Takuto Narita, Teruaki Enoto +12
Magnetars are neutron stars with extremely high magnetic fields that exhibit various X-ray phenomena such as sporadic sub-second bursts, long-term persistent flux enhancements, and…
Progenitor constraint using line ratios of the CNO elements in supernova remnants
Hiroyuki Uchida, Takuto Narita
Unveiling the nature of progenitors is crucial for understanding the origin and the mechanism of core-collapse and thermonuclear supernovae (SNe). While several methods have been d…
Global deceleration and inward movements of X-ray knots and rims of RCW 103
Hiromasa Suzuki, Takaaki Tanaka, Tsuyoshi Inoue +2
Kinematics of shocks, ejecta knots, and the compact remnant of a supernova remnant gives an insight into the nature of the progenitor and surrounding environment. We report on a pr…
Progenitor constraint with circumstellar material for the magnetar-hosting supernova remnant RCW 103
Takuto Narita, Hiroyuki Uchida, Takashi Yoshida +2
Stellar winds blown out from massive stars () contain precious information on the progenitor itself, and in this context, the most important elements are carbo…
