TOI-1468: A system of two transiting planets, a super-Earth and a mini-Neptune, on opposite sides of the radius valley
P. Chaturvedi, P. Bluhm, E. Nagel +67
We report the discovery and characterization of two small transiting planets orbiting the bright M3.0V star TOI-1468 (LSPM J0106+1913), whose transit signals were detected in the p…
Single Pulse Dispersion Measure of the Crab Pulsar
N. Lewandowska, P. B. Demorest, M. A. McLaughlin +2
We investigate the use of bright single pulses from the Crab pulsar to determine separately the dispersion measure (DM) for the Main Pulse and Interpulse components. We develop two…
Helium-like X-ray line complexes show that the hottest plasma on the O supergiant zeta Puppis is in its wind
David H. Cohen, Ariel M. Overdorff, Maurice A. Leutenegger +3
We present an analysis of Chandra grating spectra of key helium-like line complexes to put constraints on the location with respect to the photosphere of the hottest ($T \gtrsim{6…
TESS discovery of a sub-Neptune orbiting a mid-M dwarf TOI-2136
Tianjun Gan, Abderahmane Soubkiou, Sharon X. Wang +60
We present the discovery of TOI-2136b, a sub-Neptune planet transiting every 7.85 days a nearby M4.5V-type star, identified through photometric measurements from the TESS mission.…
Validation of 13 Hot and Potentially Terrestrial TESS Planets
Steven Giacalone, Courtney D. Dressing, Christina Hedges +108
The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially…
A Possible Alignment Between the Orbits of Planetary Systems and their Visual Binary Companions
Sam Christian, Andrew Vanderburg, Juliette Becker +111
Astronomers do not have a complete picture of the effects of wide-binary companions (semimajor axes greater than 100 AU) on the formation and evolution of exoplanets. We investigat…
