Nautilus: Fast Time-Resolved Spectroscopy of GKM Stellar Flares and Their Implications for Planetary Habitability
Chia-Lung Lin, Adina D. Feinstein, Jeff Valenti +10
Low-mass GKM dwarfs are prime targets for finding habitable-zone Earth-sized planets, but their frequent flares, especially on M~dwarfs, can strongly affect planetary atmospheres t…
A single power law for the TRAPPIST-1 flare distribution across four orders of magnitude in energy
Valeriy Vasilyev, Alexander I. Shapiro, Nadiia Kostogryz +10
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets' high-energy irradiation environments, with consequences for atmospheric chemis…
Unlocking HST's Stellar Treasure Trove: Stellar Activity Minima for HAT-P-11 Offer Prime Windows for Transmission Spectroscopy
Prajwal Niraula, Benjamin V. Rackham, Julien de Wit +4
HAT-P-11 is a well-studied, active K dwarf hosting an eccentric, misaligned transiting sub-Neptune. As part of the HST Stellar Treasure Trove program (HST-AR-17551), we analyze abs…
Characterizing Temperatures of Flares on the M Dwarf Wolf 359 from Simultaneous Multiband Optical Observations
Chia-Lung Lin, Li-Ching Huang, Wei-Jie Hou +2
We present a flare temperature study of the highly active M~dwarf Wolf~359 using simultaneous multiband (, , , , and ) photometric observations from the Lulin 1-m an…
Scalable, Advanced Machine Learning-based Approaches for Stellar Flare Identification: Application to TESS short-cadence Data and Analysis of a New Flare Catalogue
Chia-Lung Lin, Daniel Apai, Mark S. Giampapa +1
We apply multi-algorithm machine learning models to TESS 2-minute survey data from Sectors 1-72 to identify stellar flares. Models trained with Deep Neural Network, Random Forest,…
Mass-accretion, spectral, and photometric properties of T Tauri stars in Taurus based on TESS and LAMOST
Chia-Lung Lin, Wing-Huen Ip, Yao Hsiao +3
We present the analysis of 16 classical T Taur stars using LAMOST and TESS data, investigating spectral properties, photometric variations, and mass-accretion rates. All 16 stars e…
Simultaneous Detection of Optical Flares of the Magnetically Active M Dwarf Wolf 359
Han-Tang Lin, Wen-Ping Chen, Jinzhong Liu +13
We present detections of stellar flares of Wolf\,359, an M6.5 dwarf in the solar neighborhood (2.41~pc) known to be prone to flares due to surface magnetic activity. The observatio…
