NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit

Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53

We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates

Erika Rea, Maximilian N. Günther, George Dransfield +44

We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…

BOWIE-ALIGN: Exploring degeneracies in the muted transmission spectrum of the aligned hot Jupiter NGTS-2b with NIRSpec/G395H

Charlotte Fairman, Hannah R. Wakeford, Alastair B. Claringbold +15

We present the first atmospheric observation and characterisation of the aligned, 1468 K hot Jupiter, NGTS-2b, with one JWST NIRSpec/G395H transit. These observations complete the…

LRG-BEASTS: Detection of sodium and evidence for water absorption in the hot Saturn HAT-P-44b

Alastair B. Claringbold, Peter J. Wheatley, James Kirk +5

We present the low-resolution optical transmission spectrum of the inflated hot Saturn HAT-P-44b. The planet is a close sibling in radius (1.24 ), temperature (11…

BOWIE-ALIGN: Sub-solar C/O ratio and metallicity atmosphere of the misaligned hot Jupiter HAT-P-30b

Alastair B. Claringbold, Chloe E. Fisher, James Kirk +18

We present the JWST NIRSpec/G395H transmission spectrum of the misaligned hot Jupiter HAT-P-30b from 2.8--5.2 m as part of the BOWIE-ALIGN survey, a comparative survey designed…
