The Interstellar Laser Beacons Hypothesis and the Cosmic Lighthouses Project
Daniel Apai, Chia-Lung Lin, Kevin Wagner
In this paper, we argue that in a realistic, resource-limited scenario senders whose intent is to maximize successful communication at the lowest cost will utilize very long-lived,…
Nautilus Space Observatory: Unveiling the Diversity and Origin of Sub-Neptunes with the Nautilus Space Observatory
Luis Welbanks, Kylie E. Hall, Julien de Wit +10
Sub-Neptunes are the most common class of planets in the Galaxy, yet they have no Solar System analog and remain poorly understood as a population. JWST observations have revealed…
Mapping Stellar Heterogeneities with the Nautilus Space Observatory
Adina D. Feinstein, Jeff Valenti, Julien de Wit +9
Stellar photospheric heterogeneities, such as starspots and faculae, are a fundamental limitation for exoplanet transmission spectroscopy. Inhomogeneous surfaces can imprint wavele…
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…
Nautilus Space Observatory: The Evolution of Planets and their Atmospheres
Ilaria Pascucci, Noah Tuchow, Yifan Zhou +11
We are just beginning to explore the billion-year evolution from nascent planets in disks to mature planetary systems. Recent discoveries hint at demographic and atmospheric differ…
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…
EDEN Survey: Small Transiting Planet Detection Limits and Constraints on the Occurrence Rates for Late M Dwarfs within 15 pc
Jeremy Dietrich, Dániel Apai, Martin Schlecker +29
Earth-sized exoplanets that transit nearby, late spectral type red dwarfs will be prime targets for atmospheric characterization in the coming decade. Such systems, however, are di…
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…
