Frequent X-class Far UV Flares from a Young Solar Analog DS Tucanae A
Tristen Sextro, Kevin France, Vladimir Airapetian +4
The young solar analog DS Tuc A (~45 million years old, spectral type G6V) serves as an excellent proxy to the Sun during early stages of the Earth's evolution. The young Sun's enh…
Systematic and Statistical Properties of Prominence Eruptions on the M-dwarf YZ CMi
Yuto Kajikiya, Kosuke Namekata, Yuta Notsu +4
M-dwarfs produce frequent flares, and their associated mass ejections are expected to significantly affect the habitability of close-in exoplanets. Recent spectroscopic observation…
Broadband 12-26 GHz Radio Radiation Reveals Evidence for Micro-flares on AU Mic
Isaiah I. Tristan, Rachel A. Osten, Yuta Notsu +2
We present sequential 12-18 and 18-26 GHz radio-band (, ) VLA observations of the 22 Myr dM1e star AU Mic. We detect two flares and two marginal events over a total of 3 con…
Magnetic Heating Across the Sun and Solar-like Stars: Universal Scaling Laws from Chromospheres to Coronae
Shin Toriumi, Kosuke Namekata, Yuta Notsu +2
Magnetic activity in cool stars governs the thermal structure and high-energy radiative output of their outer atmospheres, thereby influencing stellar evolution, stellar winds, and…
Stellar Forcing of (exo)Planetary Environments
Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13
The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…
X-ray and Hα superflare on an RS CVn-type star, UX Arietis: Constraint on the flare location from radial velocity change during the flare
Sota Urabe, Yohko Tsuboi, Kosuke Namekata +5
We report on a giant stellar flare from the RS CVn-type binary UX Arietis, detected with the Monitor of All-sky X-ray Image (MAXI) and followed by a 12-day optical spectroscopic ca…
