  • Spot Activity of the RS Canum Venaticorum Star Σ Geminorum⋆

Merritt Blvd., Box 9501, Nashville, TN 37209, USA Received 14 February 2013 / Accepted 6 November 2013 ABSTRACT Aims. We model the photometry of RS CVn star σ Geminorum to obtain new information on the changes of the surface starspot distribution, that is, activity cycles, differential rotation, and active longitudes. Methods. We used the previously published continuous period search (CPS) method to analyse V-band differential photometry ob- tained between the years 1987 and 2010 with the T3 0.4 m Automated Telescope at the Fairborn Observatory. The CPS method divides data into short subsets and then models the light-curves with Fourier-models of variable orders and provides estimates of the mean magnitude, amplitude, period, and light-curve minima. These light-curve parameters are then analysed for signs of activity cycles, differential rotation and active longitudes. d Results. We confirm the presence of two previously found stable active longitudes, synchronised with the orbital period Porb = 19.60, and found eight events where the active longitudes are disrupted. The epochs of the primary light-curve minima rotate with a shorter d period Pmin,1 = 19.47 than the orbital motion.

Hutcheon Submitted in accordance with the requirements for the degree of Doctor of Philosophy. Research Institute: School of Environmental and Physical Sciences and Applied Mathematics. University of Keele June 2015 ii iii Abstract This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries. Part I investigates kinematical biases between two methods of detecting exoplanets; the ground based transit and radial velocity methods. Distances of the host stars from each method lie in almost non-overlapping groups. Samples of host stars from each group are selected. They are compared by means of matching comparison samples of stars not known to have exoplanets. The detection methods are found to introduce a negligible bias into the metallicities of the host stars but the ground based transit method introduces a median age bias of about -2 Gyr.

Me´ndez1 Departamento de Astronom«õa, Universidad de Chile, Santiago, Chile; [email protected], [email protected] ABSTRACT Astrometric measurements for 25 red dwarf systems are presented, including the first definitive trigonometric par- allaxes for 20 systems within 10 pc of the Sun, the horizon of the RECONS sample. The three nearest systems that had no previous trigonometric parallaxes (other than perhaps rough preliminary efforts) are SO 0253+1652 (3:84 Æ 0:04 pc, the 23rd nearest system), SCR 1845À6357 AB (3:85 Æ 0:02 pc, 24th nearest), and LHS 1723 (5:32 Æ 0:04 pc, 56th nearest). In total, seven of the systems reported here rank among the nearest 100 stellar systems. Sup- porting photometric and spectroscopic observations have been made to provide full characterization of the systems, including complete VRIJHKs photometry and spectral types. A study of the variability of 27 targets reveals six ob- vious variable stars, including GJ 1207, for which we observed a flare event in the V band that caused it to brighten by 1.7 mag.

S.

The characterisation of the atmosphere of exoplanets is one of the main goals of exoplanet science in the coming decades. Aims. We investigate the detectability of atmospheric spectral features of Earth-like planets in the habitable zone (HZ) around M dwarfs with the future James Webb Space Telescope (JWST). Methods. We used a coupled 1D climate-chemistry-model to simulate the influence of a range of observed and modelled M-dwarf spectra on Earth-like planets. The simulated atmospheres served as input for the calculation of the transmission spectra of the hy- pothetical planets, using a line-by-line spectral radiative transfer model. To investigate the spectroscopic detectability of absorption bands with JWST we further developed a signal-to-noise ratio (S/N) model and applied it to our transmission spectra. Results. High abundances of methane (CH4) and water (H2O) in the atmosphere of Earth-like planets around mid to late M dwarfs increase the detectability of the corresponding spectral features compared to early M-dwarf planets.

  • Further Defining Spectral Type" Y" and Exploring the Low-Mass End of The

Gelinoa, Michael C. Cushingb, Gregory N. Macec Roger L. Griffitha, Michael F. Skrutskied, Kenneth A. Marsha, Edward L. Wrightc, Peter R. Eisenhardte, Ian S. McLeanc, Amanda K. Mainzere, Adam J. Burgasserf , C. G. Tinneyg, Stephen Parkerg, Graeme Salterg ABSTRACT We present the discovery of another seven Y dwarfs from the Wide-field In- frared Survey Explorer (WISE). Using these objects, as well as the first six WISE Y dwarf discoveries from Cushing et al., we further explore the transition between spectral types T and Y. We find that the T/Y boundary roughly coincides with the spot where the J − H colors of brown dwarfs, as predicted by models, turn back to the red. Moreover, we use preliminary trigonometric parallax measure- ments to show that the T/Y boundary may also correspond to the point at which the absolute H (1.6 µm) and W2 (4.6 µm) magnitudes plummet. We use these discoveries and their preliminary distances to place them in the larger context of the Solar Neighborhood. We present a table that updates the entire stellar and substellar constinuency within 8 parsecs of the Sun, and we show that the cur- rent census has hydrogen-burning stars outnumbering brown dwarfs by roughly a factor of six. This factor will decrease with time as more brown dwarfs are iden- tified within this volume, but unless there is a vast reservoir of cold brown dwarfs arXiv:1205.2122v1 [astro-ph.SR] 9 May 2012 aInfrared Processing and Analysis Center, MS 100-22, California Institute of Technology, Pasadena, CA 91125; [email protected] bDepartment of Physics and Astronomy, MS 111, University of Toledo, 2801 W.

Photometry was obtained through filters F110W, F180M, F207M, and F222M using NICMOS Camera 2. These filters were selected to permit clear identification of cool brown dwarfs through methane contrast imaging. With a plate scale of 76 mas pixel−1, NICMOS can easily resolve binaries with subarcsecond separations in the 19.5×19.5 field of view. We previously reported five companions to nearby M and L dwarfs from this search. No new companions were discovered during the second phase of data analysis presented here, confirming that stellar/substellar binaries are rare. We establish magnitude and separation limits for which companions can be ruled out for each star in the sample, and then perform a comprehensive sensitivity and completeness analysis for the subsample of 138 M dwarfs in 126 systems.
