      Jackman, James A.G.; Wheatley, Peter J.; Pugh, Chloe E.; Kolotkov, Dmitrii Y.; Broomhall, Anne Marie; Kennedy, Grant M.; Murphy, Simon J.; Raddi, Roberto; Burleigh, Matthew R.; Casewell, Sarah L.; Eigmüller, Philipp; Gillen, Edward; Günther, Maximilian N.; Jenkins, James Stewart (Oxford University Press, 2019)
      We present the detection of an energetic flare on the pre-main-sequence M3 star NGTS J121939.5–355557, which we estimate to be only 2 Myr old. The flare had an energy of 3.2 ±0 0 4 3 ×1036 erg and a fractional amplitude ...

      West, Richard G.; Gillen, Edward; Bayliss, Daniel; Burleigh, Matthew R.; Delrez, Laetitia; Günther, Maximilian N.; Hodgkin, Simon T.; Jackman, James A.G.; Jenkins, James Stewart; King, George; McCormac, James; Nielsen, Louise D.; Raynard, Liam; Smith, Alexis M.S.; Soto, Mar (Oxford University Press, 2019)
      We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34 d orbit. NGTS-4b has a mass M = 20.6 ± 3.0M⊕ and radius R = 3.18 ± 0.26 R⊕, which places it well within the ...
