The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk
Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35
We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…
TIC-65910228 b / NGTS-38 b, a 180 day transiting warm super-Jupiter
Toby Rodel, Solène Ulmer-Moll, Samuel Gill +63
We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of R and a mass of M on a long-…
Brightness, Colour, Polarisation: A Multi-Instrument Observation Campaign of the Gorizont-6 Satellite
Robert J. S Airey, Paul Chote, Klaas Wiersema +15
We present a coordinated multi-instrument photometric and polarimetric study of the defunct geosynchronous satellite, Gorizont-6. This observation campaign combined wide-field mult…
High-Precision Photometry with a scientific CMOS Camera: II On-Sky Testing of the Marana camera at the NGTS facility
Ioannis Apergis, Daniel Bayliss, Paul Chote +24
Modern scientific CMOS cameras offer very fast readout speeds and low read noise. In this study, we evaluate the performance of the Andor Marana CMOS camera through on-sky testing…
A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP
Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53
Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…
High-Precision Photometry with a scientific CMOS Camera: I Lab Testing of the Marana camera
Ioannis Apergis, Daniel Bayliss, Leonidas Asimakoulas +6
Scientific CMOS cameras are becoming increasingly prevalent in modern observational astronomy. We assess the ability of CMOS image sensors technology to perform high-precision phot…
