High Resolution Spectroscopic Analysis of Chromospheric Line Evolution during an Energetic Flare on AD Leo
Younghun Oh, Seo-Won Chang, Jongchul Chae +6
Active M dwarfs exhibit frequent and energetic flares that provide a unique laboratory for studying chromospheric heating processes under extreme magnetic activity. To probe the fl…
A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst
Yu-Han Yang, Eleonora Troja, Brendan O'Connor +24
Observationally, Kilonovae are astrophysical transients powered by the radioactive decay of nuclei heavier than iron, synthesized in the merger of two compact objects. Over the fir…
Spatially Dependent Photometric Activity of M dwarfs in the Solar Cylinder
Seo-Won Chang, Christian Wolf, Christopher A. Onken
We study the relationship between Galactic location () and photometric activity for 3.6 million M dwarf stars within 1 kpc of the Sun. For this purpose, we identify 906 uniqu…
GECKO Optical Follow-up Observation of Three Binary Black Hole Merger Events: GW190408_181802, GW190412, and GW190503_185404
Joonho Kim, Myungshin Im, Gregory S. H. Paek +12
We present optical follow-up observation results of three binary black hole merger (BBH) events, GW190408_181802, GW190412, and GW190503_185404, which were detected by the Advanced…
SkyMapper Optical Follow-up of Gravitational Wave Triggers: Alert Science Data Pipeline and LIGO/Virgo O3 Run
Seo-Won Chang, Christopher A. Onken, Christian Wolf +7
We present an overview of the SkyMapper optical follow-up program for gravitational-wave event triggers from the LIGO/Virgo observatories, which aims at identifying early GW170817-…
A spectroscopically confirmed Gaia-selected sample of 318 new young stars within 200 pc
Maruša Žerjal, Adam D. Rains, Michael J. Ireland +7
In the Gaia era, the majority of stars in the Solar neighbourhood have parallaxes and proper motions precisely determined while spectroscopic age indicators are still missing for a…
