  • Activity and magnetic field structure of the Sun-like planet-hosting star HD 1237 

    Alvarado-Gómez, JD; Hussain, GAJ; Grunhut, J; Fares, R; Donati, J-F; Alecian, E; Kochukhov, O; Oksala, M; Morin, J; Redfield, S; Cohen, O; Drake, JJ; Jardine, M; Matt, Sean P.; Petit, P; Walter, FM (EDP Sciences, 2015-10-01)
    We analyse the magnetic activity characteristics of the planet-hosting Sun-like star, HD 1237, using HARPS spectro-polarimetric time-series data. We find evidence of rotational modulation of the magnetic longitudinal field ...
  • A spectro-polarimetric study of the planet-hosting G dwarf, HD 147513 

    Hussain, GAJ; Alvarado-Gómez, JD; Grunhut, J; Donati, J-F; Alecian, E; Oksala, M; Morin, J; Fares, R; Jardine, M; Drake, JJ; Cohen, O; Matt, Sean P.; Petit, P; Redfield, S; Walter, FM (EDP Sciences, 2016-01-01)
    The results from a spectro-polarimetric study of the planet-hosting Sun-like star, HD 147513 (G5V), are presented here. Robust detections of Zeeman signatures at all observed epochs indicate a surface magnetic field, with ...
