Kavli Affiliate: Sara Seager | First 5 Authors: Allyson Bieryla, Jiayin Dong, George Zhou, Jason D. Eastman, L. C. Mayorga | Summary: We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was detected as a candidate by […]

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Riccardo Arcodia, Johannes Buchner, Margherita Giustini | Summary: Quasi-periodic eruptions (QPEs) are recurring soft X-ray transients emerging from the vicinity of supermassive black holes (SMBHs) in nearby, low-mass galaxy nuclei; about ten QPE hosts have been identified thus far. Here we report the […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Khalil Farouqi, Anna Frebel, Friedrich-Karl Thielemann, , | Summary: Low-metallicity stars preserve the signatures of the first stellar nucleosynthesis events in the Galaxy, as their surface abundances reflect the composition of the interstellar medium from which they were born. Aside from primordial Big Bang nucleosynthesis, massive stars, […]

Kavli Affiliate: Michael McDonald | First 5 Authors: Catherine Cerny, Guillaume Mahler, Keren Sharon, Mathilde Jauzac, Gourav Khullar | Summary: We leverage JWST’s superb resolution to derive strong lensing mass maps of 14 clusters, spanning a redshift range of $zsim0.25 – 1.06$ and a mass range of $M_{500}sim2-12 times 10^{14}M_odot$, from the Strong LensIng and […]

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rohan P. Naidu, Jorryt Matthee, Harley Katz, Anna de Graaff, Pascal Oesch | Summary: The physical processes that led to the formation of billion solar mass black holes within the first 700 million years of cosmic time remain a puzzle. Several theoretical scenarios have been proposed […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alyssa R. Jankowski, Juliette Becker, Melinda Soares-Furtado, Andrew Vanderburg, Zijun He | Summary: Ultra-short-period (USP) planets are a rare but dynamically significant subset of the exoplanet sample, and understanding their dynamical histories and migration processes is necessary to build a complete picture of the outcomes of planet […]

Kavli Affiliate: Eric D. Miller | First 5 Authors: Yukikatsu Terada, Megumi Shidatsu, Makoto Sawada, Takashi Kominato, So Kato | Summary: This paper describes the development, design, ground verification, and in-orbit verification, performance measurement, and calibration of the timing system for the X-Ray Imaging and Spectroscopy Mission (XRISM). The scientific goals of the mission require […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Terese T. Hansen, Ian U. Roederer, Shivani P. Shah, Rana Ezzeddine, Timothy C. Beers | Summary: Context. Over the past few years, the $R$-Process Alliance (RPA) has successfully carried out a search for stars that are highly enhanced in elements produced via the rapid neutron-capture ($r$-) process. […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ruth M. E. Kelly, Herman L. Marshall, Silvia Zane, Nabil Brice, Swati Ravi | Summary: X-ray polarimetry offers a unique window into neutron star physics and can provide answers to questions that cannot otherwise be probed. The up-and-coming REDSoX sounding rocket mission will be the first […]
