Phase-resolved Hubble Space Telescope WFC3 Spectroscopy of Weakly-Irradiated Brown Dwarf GD 1400 and Energy Redistribution-Irradiation Trends in Six WDBD Binaries

Rachael C. Amaro, Dániel Apai, Yifan Zhou +8

Irradiated brown dwarfs offer a unique opportunity to bridge the gap between stellar and planetary atmospheres. We present high-quality /WFC3/G141 phase-resolved spec…

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,…

The only inflated brown dwarf in an eclipsing white dwarf-brown dwarf binary: WD1032+011B

Jenni R. French, Sarah L. Casewell, Rachael C. Amaro +9

Due to their short orbital periods and relatively high flux ratios, irradiated brown dwarfs in binaries with white dwarfs offer better opportunities to study irradiated atmospheres…

Atmospheric Retrievals of the Phase-resolved Spectra of Irradiated Brown Dwarfs WD-0137B and EPIC-2122B

Joshua D. Lothringer, Yifan Zhou, Daniel Apai +3

We present an atmospheric retrieval analysis of HST/WFC3/G141 spectroscopic phase curve observations of two brown dwarfs, WD-0137B and EPIC-2122B, in ultra-short period orbits arou…

Time-resolved Hubble Space Telescope Wide Field Camera 3 Spectrophotometry Reveals Inefficient Day-to-Night Heat Redistribution in the Highly Irradiated Brown Dwarf SDSS 1557B

Rachael C. Amaro, Daniel Apai, Ben W. P. Lew +8

Brown dwarfs in ultra-short period orbits around white dwarfs offer a unique opportunity to study the properties of tidally-locked, fast rotating (1-3 hr), and highly-irradiated at…

Searching for technosignatures in exoplanetary systems with current and future missions

Jacob Haqq-Misra, Edward W. Schwieterman, Hector Socas-Navarro +9

Technosignatures refer to observational manifestations of technology that could be detected through astronomical means. Most previous searches for technosignatures have focused on…
