Improving the Physical Interpretability of Gaussian Processes in Stellar Activity Modeling: A Study Case on Photometric Variability Among Stellar Clusters
Leslie Moranta, Jonathan Gagné, Jacqueline K. Faherty +12
Gaussian Processes (GPs) are widely used to model stellar variability in photometric surveys, but a statistically successful fit does not guarantee that the inferred hyperparameter…
Spectroscopic Characterization of WD J000801.25-350450 and its Two Co-Moving Companions
Peter A. Jałowiczor, Thomas P. Bickle, J. Davy Kirkpatrick +18
We present new spectroscopic data for Gaia DR3 2309499817384726016 (WD0008-350A) and its two wide, co-moving, low-mass companions. We confirm the white dwarf is a hydrogen-rich DA,…
Accurate and Model Independent Radius Determination of Single FGK and M Dwarfs Using Gaia DR3 Data
Rocio Kiman, Timothy D. Brandt, Jacqueline K. Faherty +1
Measuring fundamental stellar parameters is key to fully comprehending the evolution of stars. However, current theoretical models over-predict effective temperatures, and under-pr…
Thirteen New M Dwarf + T Dwarf Pairs Identified with WISE/NEOWISE
Federico Marocco, J. Davy Kirkpatrick, Adam C. Schneider +31
We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using WISE/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 project…
Species Syzygy: Which Animal Has Seen the Most Total Solar Eclipses?
Mark Popinchalk
A Total Solar Eclipse (TSE) is a shocking and sublime experience. In just a week hundreds of millions of Homo Sapiens will attempt to see the 2024 eclipse as it stretches across th…
89 New Ultracool Dwarf Co-Moving Companions Identified With The Backyard Worlds: Planet 9 Citizen Science Project
Austin Rothermich, Jacqueline K. Faherty, Daniella Bardalez-Gagliuffi +43
We report the identification of 89 new systems containing ultracool dwarf companions to main sequence stars and white dwarfs, using the citizen science project Backyard Worlds: Pla…
The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
Improving Undergraduate Astronomy Students' Skills with Research Literature via Accessible Summaries: An Exploratory Case Study with Astrobites-based Reading Assignments
Briley L. Lewis, Abygail R. Waggoner, Emma Clarke +17
Undergraduate physics and astronomy students are expected to engage with scientific literature as they begin their research careers, but reading comprehension skills are rarely exp…
Party Planning the Next True Happy New Year: Lunar Orbital Evolution Epochs with Integer Synodic Months Per Year
Mark Popinchalk
Humans like to party, and New Year celebrations are a great way to do that. However New Years celebrations that rely on an orbital year don't line up with those that use a Lunar Ca…
Examining the Rotation Period Distribution of the 40 Myr Tucana-Horologium Association with TESS
Mark Popinchalk, Jacqueline K. Faherty, Jason L. Curtis +6
The Tucana-Horologium Association (Tuc-Hor) is a 40 Myr old moving group in the southern sky. In this work, we measure the rotation periods of 313 Tuc-Hor objects with TESS light c…
Discovery of a Mid-L Dwarf Companion to the L 262-74 System
Léopold Gramaize, Adam C. Schneider, Federico Marocco +9
We present the discovery of CWISE J151044.74524923.5, a wide low-mass companion to the nearby (24.7 pc) system L 262-74, which was identified through the Backyard Worlds:…
From Data to Software to Science with the Rubin Observatory LSST
Katelyn Breivik, Andrew J. Connolly, K. E. Saavik Ford +97
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) dataset will dramatically alter our understanding of the Universe, from the origins of the Solar System to the…
The Oceanus Moving Group: A New 500 Myr-Old Host for the Nearest Brown Dwarf
Jonathan Gagné, Leslie Moranta, Jacqueline K. Faherty +5
We report the discovery of the Oceanus moving group, a 500 Myr-old group with 50 members and candidate members at distances 2-50 pc from the Sun using an unsupervised clu…
Using stellar rotation to identify tidally stripped members of the Praesepe open cluster
Jessica McDivitt, Stephanie T. Douglas, Jason Lee Curtis +2
As an open cluster orbits the Milky Way, gravitational fields distort it, stripping stars from the core and forming tidal tails. Recent work has identified tidal tails of the Praes…
First Detections of Exop(lan)ets: Observations and Follow-Ups of the Floofiest Transits on Zoom
Sabina Sagynbayeva, Briley L. Lewis, Graham M. Doskoch +16
With the proliferation of online Zoom meetings as a means of doing science in the 2020s, astronomers have made new and unexpected Target of Opportunity (ToO) observations. Chief am…
