      HIP 41378 f is a temperate 9.2 ± 0.1 R⊕ planet with period of 542.08 d and an extremely low density of 0.09 ± 0.02 g cm−3. It transits the bright star HIP 41378 (V=8.93),making it an exciting target for atmospheric ...
    • Long-term stellar activity variations and their effect on radial-velocity measurements 
      Costes, Jean C.; Watson, Christopher; de Mooij, Ernst; Saar, Steven H.; Dumusque, Xavier; Cameron, Collier; Phillips, David F.; Günther, Maximilian N.; Jenkins, James Stewart; Mortier, Annelies; Thompson, Andrew P. G. (Oxford Univ Press, England, 2021)
      Long-term stellar activity variations can affect the detectability of long-period and Earth-analogue extrasolar planets. We have, for 54 stars, analysed the long-term trend of five activity indicators: logR HK, the ...
    • NGTS-19b: a high-mass transiting brown dwarf in a 17-d eccentric orbit 
      Acton, Jack S.; Goad, Michael R.; Burleigh, Matthew R.; Casewell, Sarah L.; Breytenbach, Hannes; Nielsen, Louise D.; Smith, Gareth; Anderson, David R.; Battley, Matthew P.; Bayliss, Daniel; Bouchy, François; Bryant, Edward M.; Csizmadia, Szilárd; Eigmüller, Philipp; Gill, Samuel; Gillen, Edward; Grieves, Nolan; Günther, Maximilian N.; Henderson, Beth A.; Hodgkin, Simon T.; Jackman, James A. G.; Jenkins, James Stewart; Lendl, Monika; McCormac, James; Moyano, Maximiliano; Nelson, Richard P.; Sefako, Ramotholo R.; Smith, Alexis M. S.; Stalport, Manu; Thomas, Jessymol K.; Tilbrook, Rosanna H.; Udry, Stéphane; West, Richard; Wheatley, Peter J.; Worters, Hannah L.; Vines, José I.; Alves Rodrigues, Douglas (Oxford University Press, 2021)
      We present the discovery of NGTS-19b, a high-mass transiting brown dwarf discovered by the Next Generation Transit Survey. We investigate the system using follow-up photometry from the South African Astronomical Observatory, ...
    • Unmasking the hidden NGTS-3Ab: A hot Jupiter in an unresolved binary system 
      Günther, Maximilian N.; Queloz, Didier; Gillen, Edward; Delrez, Laetitia; Bouchy, François; McCormac, James; Smalley, Barry; Almleaky, Yaseen; Armstrong, David J.; Bayliss, Daniel; Burdanov, Artem; Burleigh, Matthew; Cabrera, Juan; Casewell, Sarah L.; Cooke, Benjamin F; Csizmadia, Szilárd; Ducrot, Elsa; Eigmuller, Philipp; Erikson, Anders; Gänsicke, Boris; Gibsonq, Neale; Gillon, Michaël; Goad, Michael; Jehin, Emmanuël; Jenkins, James Stewart; Louden, Tom; Moyano, Maximiliano; Murray, Catriona; Pollacco, Don; Poppenhaeger, Katja; Rauer, Heike; Raynard, Liam; Smith, Alexis; Sohy, Sandrine; Thompson, Samantha; Udry, Stéphane; Watson, Christopher; West, Richard; Wheatley, Peter (Oxford University Press, 2018)
      We present the discovery of NGTS-3Ab, a hot Jupiter found transiting the primary star of an unresolved binary system. We develop a joint analysis of multi-colour photometry, centroids, radial velocity (RV) cross-correlation ...
