    • An astro-comb calibrated solar telescope to search for the radial velocity signature of Venus 

      Phillips, David F.; Glenday, Alex; Dumusque, Xavier; Buchschacher, Nicolas; Cameron, Andrew Collier; Cecconi, Massimo; Charbonneau, David; Cosentino, Rosario; Ghedina, Adriano; Haywood, Raphaelle D.; Latham, David Winslow; Li, Chih-Hao; Lodi, Marcello; Lovis, Christophe; Molinari, Emilio; Pepe, Francesco; Sasselov, Dimitar D.; Szentgyorgyi, Andrew H.; Udry, Stephane; Walsworth, Ronald Lee (2016)
      We recently demonstrated sub-m/s sensitivity in measuring the radial velocity (RV) between the Earth and Sun using a simple solar telescope feeding the HARPS-N spectrograph at the Italian National Telescope, which is ...
    • HARPS-N Observes the Sun as a Star 

      Dumusque, Xavier; Glenday, Alex; Phillips, David F.; Buchschacher, Nicolas; Cameron, Andrew Collier; Cecconi, Massimo; Charbonneau, David; Cosentino, Rosario; Ghedina, Adriano; Latham, David Winslow; Li, Chih-Hao; Lodi, Marcello; Lovis, Christophe; Molinari, Emilio; Pepe, Francesco; Udry, Stéphane; Sasselov, Dimitar D.; Szentgyorgyi, Andrew H.; Walsworth, Ronald Lee (IOP Publishing, 2015)
      Radial velocity (RV) perturbations induced by stellar surface inhomogeneities including spots, plages and granules currently limit the detection of Earth-twins using Doppler spectroscopy. Such stellar noise is poorly ...
