Possible X-ray Quasi-Periodic Eruptions in a Tidal Disruption Event Candidate

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Megan Masterson, Margherita Giustini, Giovanni Miniutti | Summary: X-ray Quasi-Periodic Eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high amplitude soft X-ray flares that recur on timescales of hours, but what causes […]

TOI-2285b: A 1.7 Earth-radius Planet Near the Habitable Zone around a Nearby M Dwarf

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Akihiko Fukui, Tadahiro Kimura, Teruyuki Hirano, Norio Narita, Takanori Kodama | Summary: We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 days. We identified the transit signal from the Transiting Exoplanet Survey Satellite photometric data, […]

TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt, Madyson G. Barber, James E. Owen | Summary: Mature super-Earths and sub-Neptunes are predicted to be $simeq$Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15$R_oplus$ planets around young stars even if their older counterparts […]

Calibration and Performance of the REgolith X-Ray Imaging Spectrometer (REXIS) Aboard NASA’s OSIRIS-REx Mission to Bennu

Kavli Affiliate: Rebecca Masterson | First 5 Authors: Jaesub Hong, Richard P. Binzel, Branden Allen, David Guevel, Jonathan Grindlay | Summary: The REgolith X-ray Imaging Spectrometer (REXIS) instrument on board NASA’s OSIRIS-REx mission to the asteroid Bennu is a Class-D student collaboration experiment designed to detect fluoresced X-rays from the asteroid’s surface to measure elemental […]

TKS V. Twin sub-Neptunes Transiting the Nearby G Star HD 63935

Kavli Affiliate: Avi Shporer | First 5 Authors: Nicholas Scarsdale, Joseph M. Akana Murphy, Natalie M. Batalha, Ian J. M. Crossfield, Courtney D. Dressing | Summary: We present the discovery of two nearly identically-sized sub-Neptune transiting planets orbiting HD 63935, a bright ($V=8.6$ mag), sun-like ($T_{eff}=5560K$) star at 49 pc. TESS identified the first planet, […]

A Malmquist-like bias in the inferred areas of diamond caustics and the resulting bias in inferred time delays for gravitationally lensed quasars

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Derek Baldwin, Paul L. Schechter, , , | Summary: Quadruply lensed quasars are visible only when the source quasar lies within the diamond caustic of the lensing galaxy. This condition creates a Malmquist-like selection effect in the population of observed quadruply lensed quasars, increasing the true […]

A Malmquist-like bias in the inferred areas of diamond caustics and consequences for inferred time delays of gravitationally lensed quasars

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Derek Baldwin, Paul L. Schechter, , , | Summary: Quasars are quadruply lensed only when they lie within the diamond caustic of a lensing galaxy. This precondition produces a Malmquist-like selection effect in observed populations of quadruply lensed quasars, overestimating the true caustic area. The bias […]

Quick-Look Pipeline Lightcurves for 9.1 Million Stars Observed Over the First Year of the TESS Extended Mission

Kavli Affiliate: George Ricker | First 5 Authors: Michelle Kunimoto, Chelsea Huang, Evan Tey, Willie Fong, Katharine Hesse | Summary: We present a magnitude-limited set of lightcurves for stars observed over the TESS Extended Mission, as extracted from full-frame images (FFIs) by MIT’s Quick-Look Pipeline (QLP). QLP uses multi-aperture photometry to produce lightcurves for ~1 […]
