Spinning up a Daze: TESS Uncovers a Hot Jupiter orbiting the Rapid-Rotator TOI-778
Jake Clark, Brett Addison, Jack Okumura +68
NASA's Transiting Exoplanet Survey Satellite (TESS) mission, has been uncovering a growing number of exoplanets orbiting nearby, bright stars. Most exoplanets that have been discov…
Hubble Space Telescope transmission spectroscopy for the temperate sub-Neptune TOI-270d: a possible hydrogen-rich atmosphere containing water vapour
Thomas Mikal-Evans, Nikku Madhusudhan, Jason Dittmann +6
TOI-270d is a temperate sub-Neptune discovered by the Transiting Exoplanet Survey Satellite (TESS) around a bright (J=9.1mag) M3V host star. With an approximate radius of 2RE and e…
Precise near-infrared photometry, accounting for precipitable water vapour at SPECULOOS Southern Observatory
Peter P. Pedersen, C. A. Murray, D. Queloz +20
The variability induced by precipitable water vapour (PWV) can heavily affect the accuracy of time-series photometric measurements gathered from the ground, especially in the near-…
NGTS-21b: An Inflated Super-Jupiter Orbiting a Metal-poor K dwarf
Douglas R. Alves, James S. Jenkins, Jose I. Vines +29
We report the discovery of NGTS-21b, a massive hot Jupiter orbiting a low-mass star as part of the Next Generation Transit Survey (NGTS). The planet has a mass and radius of $2.36…
TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf
Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson +137
We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ( mag), high proper motion…
HD 28109 hosts a trio of transiting Neptunian planets including a near-resonant pair, confirmed by ASTEP from Antarctica
Georgina Dransfield, Amaury H. M. J. Triaud, Tristan Guillot +28
We report on the discovery and characterisation of three planets orbiting the F8 star HD~28109, which sits comfortably in \tess's continuous viewing zone. The two outer planets hav…
X-ray emission from candidate stellar merger remnant TYC 2597-735-1 and its Blue Ring Nebula
Hans Moritz Günther, Keri Hoadley, Maximilian N. Günther +3
Tight binary or multiple star systems can interact through mass transfer and follow vastly different evolutionary pathways than single stars. The star TYC 2597-735-1 is a candidate…
Theoretical and Observational Evidence for Coriolis Effects in Coronal Magnetic Fields Via Direct Current Driven Flaring Events
Darryl Z. Seligman, Leslie A. Rogers, Adina D. Feinstein +6
All stars produce explosive surface events such as flares and coronal mass ejections. These events are driven by the release of energy stored in coronal magnetic fields, generated…
