The Astronomy of Halakhic Nightfall: Calculating Ts'eit HaKokhavim and Motsa'ei Shabbat
Aster G. Taylor
In Jewish tradition, the boundary between days is not midnight, but nightfall. Nightfall is when one must pray ma'ariv, count the omer, and may engage in activity after Shabbat. Wh…
The Effects of Magnetic Accretion on the Spatial Extent of White Dwarf Pollution
Dang Pham, Aster G. Taylor, Tim Cunningham
Many white dwarfs are polluted by metals, which are generally understood to be the accreted remnants of a planetary system. Modeling these systems typically assumes that the metal…
A Retrieval Framework for Observationally Constraining the Parameters of Circumplanetary Disks
Aster Taylor, Fred Adams
As they form, giant planets are surrounded by disks of gas and dust sourced from the background circumstellar disk. Although there have been few detections to date, upcoming instru…
The Two-Dimensional Structure of Circumplanetary Disks and their Radiative Signatures
Aster G. Taylor, Fred C. Adams, Nuria Calvet
During their formative stages, giant planets are fed by infalling material sourced from the background circumstellar disk. Due to conservation of angular momentum, the incoming gas…
Onset of CN Emission in 3I/ATLAS: Evidence for Strong Carbon-Chain Depletion
Luis E. Salazar Manzano, Hsing Wen Lin, Aster G. Taylor +6
Interstellar objects provide a direct window into the environmental conditions around stars other than the Sun. The recent discovery of 3I/ATLAS, a new interstellar comet, offers a…
Potential Thermal Profiles of The Third Interstellar Object 3I/ATLAS
Atsuhiro Yaginuma, Aster G. Taylor, Darryl Z. Seligman
We investigate the thermal evolution of 3I/ATLAS, the third macroscopic interstellar object discovered on 2025 July 1. By comparing modeled thermal profiles with observations of vo…
Theoretical Mass Function for Secondaries Forming via Gravitational Instability in Circumstellar Disks
Fred C. Adams, Aster G. Taylor, Michael R. Meyer
This paper constructs a theoretical framework for calculating the distribution of masses for secondary bodies forming via gravitational instability in the outer regions of circumst…
The Kinematic Age of 3I/ATLAS and its Implications for Early Planet Formation
Aster G. Taylor, Darryl Z. Seligman
The recent discovery of the third interstellar object (3I/ATLAS) expands the known census from two to three and significantly improves statistical inferences regarding the underlyi…
Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
Darryl Z. Seligman, Marco Micheli, Davide Farnocchia +44
We report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an…
The Feasibility of a Spacecraft Flyby with the Third Interstellar Object 3I/ATLAS from Earth or Mars
Atsuhiro Yaginuma, Tessa Frincke, Darryl Z. Seligman +5
We investigate the feasibility of a spacecraft mission to conduct a flyby of 3I/ATLAS, the third macroscopic interstellar object discovered on July 1 2025, as it traverses the Sola…
Two Distinct Populations of Dark Comets Delineated by Orbits and Sizes
Darryl Z. Seligman, Davide Farnocchia, Marco Micheli +7
Small bodies are capable of delivering essential prerequisites for the development of life, such as volatiles and organics, to the terrestrial planets. For example, empirical evide…
Strong Nongravitational Accelerations and the Potential for Misidentification of Near-Earth Objects
Aster G. Taylor, Darryl Z. Seligman, Matthew J. Holman +5
Nongravitational accelerations in the absence of observed activity have recently been identified on NEOs, opening the question of the prevalence of anisotropic mass-loss in the nea…
Radiative Signatures of Circumplanetary Disks and Envelopes During the Late Stages of Giant Planet Formation
Aster G. Taylor, Fred C. Adams
During the late stages of giant planet formation, protoplanets are surrounded by a circumplanetary disk and an infalling envelope of gas and dust. For systems with sufficient cooli…
The Dynamical Origins of the Dark Comets and a Proposed Evolutionary Track
Aster G. Taylor, Jordan K. Steckloff, Darryl Z. Seligman +5
So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that exhibit nongravitational accelerations inconsistent with radiative effects. These objects…
Formation and Structure of Circumplanetary Disks and Envelopes during the Late Stages of Giant Planet Formation
Aster G. Taylor, Fred C. Adams
Giant planets are expected to form within circumstellar disks, which shape their formation history and the local environment. Here, we consider the formation and structure of circu…
