    • AD Leonis : Radial velocity signal of stellar rotation or spin-orbit resonance? 

      Tuomi, Mikko; Jones, Hugh R. A.; Anglada-Escudé, Guillem; Butler, R. Paul; Kiraga, Marcin; Vogt, Steven S. (2018-04-16)
      AD Leonis is a nearby magnetically active M dwarf. We find Doppler variability with a period of 2.23 days, as well as photometric signals: (1) a short-period signal, which is similar to the radial velocity signal, albeit ...
    • Bayesian search for low-mass planets around nearby M dwarfs. Estimates for occurrence rate based on global detectability statistics 

      Tuomi, Mikko; Jones, Hugh; Barnes, John R.; Anglada-Escudé, Guillem; Jenkins, James S. (2014-06-21)
      Due to their higher planet-star mass ratios, M dwarfs are the easiest targets for detection of low-mass planets orbiting nearby stars using Doppler spectroscopy. Furthermore, because of their low masses and luminosities, ...
    • Benchmarking the power of amateur observatories for TTV exoplanets detection 

      Baluev, Roman V.; Sokov, Evgenii N.; Shaidulin, Vakhit Sh; Sokova, Iraida A.; Jones, H.R.A.; Tuomi, Mikko; Anglada-Escudé, Guillem; Benni, Paul; Colazo, Carlos A.; Schneiter, Matias E.; D'Angelo, Carolina S. Villarreal; Burdanov, Artem Yu; Fernández-Lajús, Eduardo; Baştürk, Özgür; Hentunen, Veli-Pekka; Shadick, Stan (2015-07-01)
      We perform an analysis of ~80000 photometric measurements for the following 10 stars hosting transiting planets: WASP-2, -4, -5, -52, Kelt-1, CoRoT-2, XO-2, TrES-1, HD 189733, GJ 436. Our analysis includes mainly transit ...
    • Detection of the nearest Jupiter analog in radial velocity and astrometry data 

      Feng, Fabo; Anglada-Escudé, Guillem; Tuomi, Mikko; Jones, Hugh R. A.; Chanamé, Julio; Butler, Paul R.; Janson, Markus (2019-10-21)
      The presence of Jupiter is crucial to the architecture of the Solar System and models underline this to be a generic feature of planetary systems. We find the detection of the difference between the position and motion ...
    • GJ 832c : A super-earth in the habitable zone 

      Wittenmyer, Robert A.; Tuomi, Mikko; Butler, R. P.; Jones, Hugh; Anglada-Escudé, Guillem; Horner, Jonathan; Tinney, C. G.; Marshall, J. P.; Carter, B. D.; Bailey, J.; Salter, G. S.; O'Toole, S. J.; Wright, D.; Crane, J. D.; Schectman, S. A.; Arriagada, P.; Thompson, I.; Minniti, D.; Jenkins, J. S.; Diaz, M. (2014-08-05)
      We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly circular 9.4 yr orbit. The combination of ...
