  • Confronting standard models of proto-planetary disks with new mid-infrared sizes from the Keck Interferometer 

    Millan-Gabet, Rafael; Che, Xiao; Monnier, John D.; Sitko, Michael l.; Russell, Ray W.; Grady, Carol A.; Day, Amanda N.; Perry R.B.; Harries, Tim J.; Aarnio, Alicia N.; Colavita, Mark M.; Wizinowich, Peter L.; Ragland, Sam; Woillez, Julien (American Astronomical Society, 2016-07-26)
    We present near and mid–infrared interferometric observations made with the Keck Interferometer Nuller and near–contemporaneous spectro–photometry from the IRTF of 11 well known young stellar objects, several observed for ...
  • Coronal mass ejections and angular momentum loss in young stars 

    Aarnio, Alicia N.; Stassun, Keivan G.; Matt, Sean P. (Cambridge University Press, 2013)
    In our own solar system, the necessity of understanding space weather is readily evident. Fortunately for Earth, our nearest stellar neighbor is relatively quiet, exhibiting activity levels several orders of magnitude lower ...
  • Detecting the Companions and Ellipsoidal Variations of RS CVn Primaries. I. σ Geminorum 

    Roettenbacher, RM; Monnier, JD; Henry, G.; Fekel, FC; Williamson, MH; Pourbaix, D; Latham, DW; Latham, CA; Torres, G; Baron, F; Che, X; Kraus, Stefan; Schaefer, GH; Aarnio, Alicia N.; Korhonen, H; Harmon, RO; ten Brummelaar, TA; Sturmann, J; Sturmann, L; Turner, NH (American Astronomical Society, 2015-06-25)
    To measure the properties of both components of the RS Canum Venaticorum binary σ Geminorum (σ Gem), we directly detect the faint companion, measure the orbit, obtain model-independent masses and evolutionary histories, ...
