Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, James E. Lawler, Elizabeth A. Den Hartog, Vinicius M. Placco, Rebecca Surman | Summary: We present a nearly complete rapid neutron-capture process (r-process) chemical inventory of the metal-poor ([Fe/H] = -1.46 +/- 0.10) r-process-enhanced ([Eu/Fe] = +1.32 +/- 0.08) halo star HD 222925. This […]

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Colin Littlefield, D. W. Hoard, Peter Garnavich, Paula Szkody, Paul A. Mason | Summary: There have been relatively few published long-duration, uninterrupted light curves of magnetic cataclysmic variable stars in which the accreting white dwarf’s rotational frequency is slightly desynchronized from the binary orbital frequency (asynchronous […]

Kavli Affiliate: Andrew Vanderburg, Sara Seager | First 5 Authors: Benjamin J. Hord, Knicole D. Colón, Travis A. Berger, Veselin Kostov, Michele L. Silverstein | Summary: Hot Jupiters are generally observed to lack close planetary companions, a trend that has been interpreted as evidence for high-eccentricity migration. We present the discovery and validation of WASP-132 […]

Kavli Affiliate: Erin Kara | First 5 Authors: Kevin B. Burdge, Thomas R. Marsh, Jim Fuller, Eric C. Bellm, Ilaria Caiazzo | Summary: Over a dozen millisecond pulsars are ablating low-mass companions in close binary systems. In the original "black widow", the 8-hour orbital period eclipsing pulsar PSR J1959+2048 (PSR B1957+20), high energy emission originating […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jessica Y. -C. Yeh, Aaron Smith, Rahul Kannan, Enrico Garaldi, Mark Vogelsberger | Summary: A fundamental requirement for reionizing the Universe is that a sufficient fraction of the ionizing photons emitted by galaxies successfully escapes into the intergalactic medium. However, due to the scarcity of high-redshift observational […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Petr Kabáth, Priyanka Chaturvedi, Phillip J. MacQueen, Marek Skarka, Ján Šubjak | Summary: We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have orbital periods between 1.4 and 2.05 days. The masses […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Alexander P. Ji, Mohammad K. Mardini, Xiaowei Ou | Summary: We present chemical abundances and velocities of five stars between 0.3 kpc to 1.1 kpc from the center of the Tucana II ultra-faint dwarf galaxy (UFD) from high-resolution Magellan/MIKE spectroscopy. We find that […]
