A dynamically-packed planetary system around GJ 667C with three super-Earths in its habitable zone
Anglada-Escude, Guillem; Tuomi, Mikko; Gerlach, Enrico; Barnes, Rory; Heller, Rene; Jenkins, James S.; Wende, Sebastian; Vogt, Steven S.; Butler, R. Paul; Reiners, Ansgar; Jones, H.R.A. (2013-08-07)Context. Since low-mass stars have low luminosities, orbits at which liquid water can exist on Earth-sized planets are relatively close-in, which produces Doppler signals that are detectable using state-of-the-art Doppler ... -
The impact of unresolved magnetic spots on high precision radial velocity measurements
Lisogorskyi, Maksym; Saikia, Susdeshna Boro; Jeffers, Sandra V.; Jones, Hugh R. A.; Morin, Julien; Mengel, Matthew; Reiners, Ansgar; Vidotto, Aline A.; Petit, Pascal (2020-07-23)The Doppler method of exoplanet detection has been extremely successful, but suffers from contaminating noise from stellar activity. In this work a model of a rotating star with a magnetic field based on the geometry of ... -
A terrestrial planet candidate in a temperate orbit around Proxima Centauri
Anglada-Escude, Guillem; Amado, Pedro J.; Barnes, John; Berdinas, Zaira M.; Butler, Paul; Coleman, Gavin A. L.; de la Cueva, Ignacio; Dreizler, Stefan; Endl, Michael; Giesers, Benjamin; Jeffers, Sandra V.; Jenkins, James S.; Jones, Hugh; Kiraga, Marcin; Kurster, Martin; Lopez-Gonzalez, Maria J.; Marvin, Christopher J.; Morales, Nicolas; Morin, Julien; Nelson, Richard P.; Ortiz, Jose L.; Ofir, Aviv; Paardekooper, Sijme-Jan; Reiners, Ansgar; Rodriguez, Eloy; Rodriguez-Lopez, Cristina; Sarmiento, Luis F.; Strachan, John P.; Tsapras, Yiannis; Tuomi, Mikko; Zechmeister, Mathias (2016-08-25)At a distance of 1.295 parsecs, the red dwarf Proxima Centauri (α Centauri C, GL 551, HIP 70890 or simply Proxima) is the Sun’s closest stellar neighbour and one of the best-studied low-mass stars. It has an effective ...
