The Pandora SmallSat: post-launch operations and mission update
Trevor O. Foote, Elisa V. Quintana, Jessie L. Dotson +41
The Pandora SmallSat is a NASA flight project designed to study the atmospheres of exoplanets. Transmission spectroscopy of transiting exoplanets provides our best opportunity to i…
Small-Body Science with the Nautilus Space Observatory: From Cislunar Space Resilience to Mapping the Kuiper-Belt-to-Oort-Cloud Transition
J. de Wit, A. Y. Burdanov, P. McGill +3
A new generation of space-based observatories can transform small-body science from the local Earth-Moon environment to the Solar System's dynamical frontier, where planetary contr…
A Scalable Path to Astrometric Exomoon Discoveries with the Nautilus Space Observatory
Kevin Wagner, Sumin Seung, Dániel Apai +13
Moons orbiting exoplanets (exomoons) can be detected through the reflex motion they impart to their host planet, which is recoverable in relative star-planet astrometric time serie…
NASA's Pandora SmallSat Mission: Simulating the Impact of Stellar Photospheric Heterogeneity and Its Correction
Benjamin V. Rackham, Aishwarya R. Iyer, Dániel Apai +28
Stellar photospheric heterogeneity is a dominant astrophysical systematic impacting exoplanet transmission spectroscopy. NASA's Pandora SmallSat Mission is designed to address this…
NASA's Pandora SmallSat Mission: Simulated Modeling and Retrieval of Near-Infrared Exoplanet Transmission Spectra
Yoav Rotman, Peter McGill, Luis Welbanks +22
Pandora is a SmallSat mission dedicated to understanding exoplanets and their host stars by disentangling the impact of stellar heterogeneity on exoplanet transmission spectra. Sel…
Challenges in the detection of gases in exoplanet atmospheres
Luis Welbanks, Matthew C. Nixon, Peter McGill +12
Claims of detections of gases in exoplanet atmospheres often rely on comparisons between models including and excluding specific chemical species. However, the space of molecular c…
Predicting Cislunar Orbit Lifetimes from Initial Orbital Elements
Denvir Higgins, Travis Yeager, Peter McGill +4
Cislunar space is the volume between Earth's geosynchronous orbit and beyond the Moon, including the lunar Lagrange points. Understanding the stability of orbits within this space…
Enabling Robust Exoplanet Atmospheric Retrievals with Gaussian Processes
Yoav Rotman, Luis Welbanks, Michael R. Line +3
Atmospheric retrievals are essential tools for interpreting exoplanet transmission and eclipse spectra, enabling quantitative constraints on the chemical composition, aerosol prope…
A High Internal Heat Flux and Large Core in a Warm Neptune Exoplanet
Luis Welbanks, Taylor J. Bell, Thomas G. Beatty +16
Interactions between exoplanetary atmospheres and internal properties have long been hypothesized to be drivers of the inflation mechanisms of gaseous planets and apparent atmosphe…
Bringing 2D Eclipse Mapping out of the Shadows with Leave-one-out Cross-validation
Ryan C. Challener, Luis Welbanks, Peter McGill
Eclipse mapping is a technique for inferring 2D brightness maps of transiting exoplanets from the shape of an eclipse light curve. With JWST's unmatched precision, eclipse mapping…
Methods for Incorporating Model Uncertainty into Exoplanet Atmospheric Analysis
Matthew C. Nixon, Luis Welbanks, Peter McGill +1
A key goal of exoplanet spectroscopy is to measure atmospheric properties, such as abundances of chemical species, in order to connect them to our understanding of atmospheric phys…
SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
Primordial Black Hole Dark Matter Simulations Using PopSyCLE
K. Pruett, W. Dawson, M. S. Medford +6
Primordial black holes (PBHs), theorized to have originated in the early universe, are speculated to be a viable form of dark matter. If they exist, they should be detectable throu…
