We report the discovery and characterization of TOI-6692 b, an eccentric (e ∼ 0.54) Jupiter on a 130 day orbit. TOI-6692 b was first detected as a community TESS Object of Interest by the Visual Survey Group and the Planet Hunters group as a single-transit candidate via TESS observation. The period was subsequently confirmed via radial velocity

For small planets orbiting within the habitable zones of their host stars, multicolour validation via photometric transit observations offers an efficient alternative to prioritize targets before intensive radial-velocity follow-up, thereby expanding the sample of habitable-zone exoplanets amenable for atmospheric characterization. In this study

To date, there has been significant interest in globular cluster (GC)-rich ultra-diffuse galaxies (UDGs) and the evidence that they have formed via an unexpected, 'failed galaxy' formation pathway. The majority of the evidence for 'failed galaxy' UDGs originates from spectroscopic observations targeting passive GC-rich UDGs, with a focus on those

The overwhelming majority of eclipsing white dwarf (WD) binary systems show quasi-periodic variations in eclipse timings on many year time-scales. Currently, the mechanism behind these eclipse time variations (ETVs) is not known, with the main competing theories being the planetary hypothesis and the Applegate/Lanza mechanisms. Here, we present a

The tens of millions of spectra being captured by the Dark Energy Spectroscopic Instrument (DESI) provide tremendous discovery potential. In this work we show how Machine Learning, in particular Variational Autoencoders (VAE), can detect anomalies in a sample of approximately 200 000 DESI spectra comprising galaxies, quasars and stars. We

LTT 9779 b is an ultra-hot Neptune (R p ≍ 4.7 R ⊕, M p ≍ 29 M ⊕) orbiting its Sun-like host star in just 19 hr, placing it deep within the "hot-Neptune desert," where Neptunian planets are seldom found. We present new James Webb Space Telescope NIRSpec G395H phase curve observations that probe its atmospheric composition in unprecedented detail. At
