TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star

Alexis Heitzmann, George Zhou, Samuel N. Quinn +47

We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< Myr). This planet stands o…

Planets around young active Solar-type stars: Assessing detection capabilities from a non stabilised spectrograph

A. Heitzmann, S. C. Marsden, P. Petit +8

Short-orbit gas giant planet formation/evolution mechanisms are still not well understood. One promising pathway to discriminate between mechanisms is to constrain the occurrence r…

Multi-wavelength, spatially resolved modelling of HD 48682's debris disc

S. Hengst, J. P. Marshall, J. Horner +1

Asteroids and comets (planetesimals) are created in gas- and dust-rich protoplanetary discs. The presence of these planetesimals around main-sequence stars is usually inferred from…

TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star

Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91

We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…
