Atmospheric Signatures of Common Envelope Evolution in White Dwarf Planets
Sydney Jenkins, Andrew Vanderburg, James Mang +4
The majority of confirmed exoplanets orbit within 1 au of a main-sequence (MS) star. When their stellar hosts evolve off the MS, many of these planets will be engulfed and destroye…
Lithium Enrichment in a Subgiant Star with a Brown Dwarf Companion: A Planetary Engulfment Candidate
Brooke Kotten, Melinda Soares-Furtado, Ricardo Yarza +11
Theoretical models predict that subgiants within a narrow mass regime can retain detectable lithium enrichment signatures from planetary engulfment. We test this prediction using T…
The Landscape of Unstable Mass Transfer in Interacting Binaries and Its Imprint on the Population of Luminous Red Novae
Angela A. G. Twum, Alejandro Vigna-Gómez, Morgan MacLeod +4
A common-envelope (CE) phase occurs when a star engulfs its companion and is widely considered the primary channel for producing Luminous Red Novae (LRNe). In this study, we combin…
Observable Metal Pollution in Main-Sequence Stars: Simulations of Rocky Planets Engulfed by Stars in the to M Range
Kaitlyn T. Lane, Alexander P. Stephan, Melinda Soares-Furtado +2
The engulfment of planets by their host stars is an expected outcome of various dynamical processes and has been invoked to explain a variety of observed stellar properties, such a…
Evolution of the ZTF SLRN-2020 star-planet merger
Ricardo Yarza, Morgan MacLeod, Benjamin Idini +2
We model the optical and infrared transient ZTF SLRN-2020, previously associated with a star-planet merger. We consider the scenario in which orbital decay via tidal dissipation le…
Black Hole Survival Guide: Searching for Stars in the Galactic Center That Endure Partial Tidal Disruption
Rewa Clark Bush, Samantha C. Wu, Rosa Wallace Everson +3
Once per 10,000-100,000 years, an unlucky star may experience a close encounter with a supermassive black hole (SMBH), partially or fully tearing apart the star in an exceedingly b…
SN 2021foa: The "Flip-Flop" Type IIn / Ibn supernova
D. Farias, C. Gall, G. Narayan +29
We present a comprehensive analysis of the photometric and spectroscopic evolution of SN~2021foa, unique among the class of transitional supernovae for repeatedly changing its spec…
The TEMPO Survey II: Science Cases Leveraged from a Proposed 30-Day Time Domain Survey of the Orion Nebula with the Nancy Grace Roman Space Telescope
Melinda Soares-Furtado, Mary Anne Limbach, Andrew Vanderburg +26
The TEMPO (Transiting Exosatellites, Moons, and Planets in Orion) Survey is a proposed 30-day observational campaign using the Nancy Grace Roman Space Telescope. By providing deep,…
Repeating Partial Tidal Encounters of Sun-like Stars Leading to their Complete Disruption
Chang Liu, Ricardo Yarza, Enrico Ramirez-Ruiz
Stars grazing supermassive black holes on bound orbits may produce periodic flares over many passages, known as repeating partial tidal disruption events (TDEs). Here, we present 3…
The Evolution of Binaries Embedded Within Common Envelopes
Alejandra Rosselli-Calderon, Ricardo Yarza, Ariadna Murguia-Berthier +5
Triple stellar systems allow us to study stellar processes that cannot be attained in binary stars. The evolutionary phases in which the stellar members undergo mass exchanges can…
TESS Hunt for Young and Maturing Exoplanets (THYME) XI: An Earth-sized Planet Orbiting a Nearby, Solar-like Host in the 400Myr Ursa Major Moving Group
Benjamin K. Capistrant, Melinda Soares-Furtado, Andrew Vanderburg +32
Young terrestrial worlds are critical test beds to constrain prevailing theories of planetary formation and evolution. We present the discovery of HD 63433d - a nearby (22pc), Eart…
SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS
Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28
The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…
Rethinking Thorne-Żytkow Object Formation: The Fate of X-ray Binary LMC X-4 and Implications for Ultra-long Gamma-ray Bursts
Tenley Hutchinson-Smith, Rosa Wallace Everson, Angela A. Twum +5
We present a start-to-end simulation aimed at studying the long-term fate of high-mass X-ray binaries and whether a Thorne-Żytkow object (TŻO) might ultimately be assembled. We ana…
A revised energy formalism for common-envelope evolution: repercussions for planetary engulfment and the formation of neutron star binaries
Ricardo Yarza, Rosa Wallace Everson, Enrico Ramirez-Ruiz
Common-envelope evolution is a stage in binary system evolution in which a giant star engulfs a companion. The standard energy formalism is an analytical framework to estimate the…
The Young Supernova Experiment Data Release 1 (YSE DR1): Light Curves and Photometric Classification of 1975 Supernovae
P. D. Aleo, K. Malanchev, S. Sharief +80
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry of 1…
Tidal disruption events from eccentric orbits and lessons learned from the noteworthy ASASSN-14ko
Chang Liu, Brenna Mockler, Enrico Ramirez-Ruiz +5
Stars grazing supermassive black holes (SMBHs) on bound orbits may survive tidal disruption, causing periodic flares. Inspired by the recent discovery of the periodic nuclear trans…

Hydrodynamics and survivability during post-main-sequence planetary engulfment
Ricardo Yarza, Naela Razo Lopez, Ariadna Murguia-Berthier +6
The engulfment of substellar bodies (SBs, such as brown dwarfs and planets) by giant stars is a possible explanation for rapidly rotating giants, lithium-rich giants, and the prese…
