Kavli Affiliate: Nathan P. Lourie | First 5 Authors: Geoffrey Mo, Kishalay De, Eli Wiston, Nayana A. J., Raffaella Margutti | Summary: Type Ia supernovae arise from the thermonuclear explosions of white dwarfs in multiple star systems. A rare sub-class of SNe Ia exhibit signatures of interaction with circumstellar material (CSM), allowing for direct constraints […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Qier An, Chelsea X. Huang, Timothy D. Brandt, Robert A. Wittenmyer | Summary: As exoplanet surveys reach ever-higher sensitivities and durations, planets analogous to the solar system giant planets are increasingly within reach. HD 28185 is a Sun-like star known to host a $msin i=6 […]

Kavli Affiliate: Sara Seager | First 5 Authors: Zifan Lin, Saverio Cambioni, Sara Seager, , | Summary: Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories – metal-rich formation hypothesis and naked core hypothesis – that explain how formation and evolution can alter the compositions and […]

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano, Eduardo J. S. Villaseñor, | Summary: The relation between the Husain-Kuchav{r} model and some extensions thereof that incorporate a dynamical time variable is explored. To this end, we rely on the geometric approach to the Hamiltonian dynamics of […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: A. M. Cook, Dayi Li, Gwendolyn M. Eadie, David C. Stenning, Paul Scholz | Summary: This paper introduces an approach to analyze nonhomogeneous Poisson processes (NHPP) observed with noise, focusing on previously unstudied second-order characteristics of the noisy process. Utilizing a hierarchical Bayesian model with noisy […]

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Michal Zajaček, Petra Suková, Vladimír Karas, Dheeraj R. Pasham, Francesco Tombesi | Summary: The first detection of the quasiperiodic ultrafast outflow in the ASASSN-20qc system was reported by Pasham et al. (2024). The outflow is revealed in the soft X-ray spectra as an absorption feature, which […]

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Ronald A. Remillard, Margarita Hernanz, Jean in ‘t Zand, Paul S. Ray, Valter Bonvicini | Summary: The Wide Field Monitor (WFM) is one of the three instruments on the Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) mission, which was proposed in response to the NASA […]

Kavli Affiliate: Sara Seager | First 5 Authors: Adam Distler, Melinda Soares-Furtado, Andrew Vanderburg, Jack Schulte, Juliette Becker | Summary: We present the discovery and characterization of TOI-4364,b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit observations and ground-based follow-up photometry. The planet orbits a bright M dwarf […]
