A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Kavli Affiliate: George R. Ricker | First 5 Authors: Marc Hon, Saul Rappaport, Avi Shporer, Andrew Vanderburg, Karen A. Collins | Summary: We report the discovery of BD+05$,$4868$,$Ab, a transiting exoplanet orbiting a bright ($V=10.16$) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) reveal variable transit […]

Effects of galactic environment on size and dark matter content in low-mass galaxies

Kavli Affiliate: Lina Necib | First 5 Authors: Francisco J. Mercado, Jorge Moreno, Robert Feldmann, Marckie Zeender, Jose A. Benavides Blanco | Summary: We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy’s environment influences its size and dark matter content. Our study focuses on approximately 1,200 galaxies (886 central and 332 satellite […]

Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Muryel Guolo, Sean Lockwood, Andrew Mummery, Dheeraj R. Pasham | Summary: X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray […]
