    Carbon and Oxygen in Nearby Stars: Keys to Protoplanetary Disk Chemistry0 Erik A. Petigura Astronomy Department, University of California, Berkeley, CA 94720 [email protected] Geoffrey W. Marcy Astronomy Department, University of California, Berkeley, CA 94720 Received ; accepted arXiv:1106.5449v1 [astro-ph.SR] 27 Jun 2011 0Based in part on observations obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. –2– ABSTRACT We present carbon and oxygen abundances for 941 FGK stars—the largest such catalog to date. We find that planet-bearing systems are enriched in these elements. We self-consistently measure NC /NO, which is thought to play a key role in planet formation. We identify 46 stars with NC /NO 1.00 as poten- ≥ tial hosts of carbon-dominated exoplanets. We measure a downward trend in [O/Fe] versus [Fe/H] and find distinct trends in the thin and thick disk, sup- porting the work of Bensby et al. (2004). Finally, we measure sub-solar NC /NO +0.11 = 0.40 0.07 for WASP-12, a surprising result as this star is host to a transiting − hot Jupiter whose dayside atmosphere was recently reported to have NC /NO ≥ 1 by Madhusudhan et al. (2011). Our measurements are based on 15,000 high signal-to-noise spectra taken with the Keck 1 telescope as part of the California Planet Search.

  • Sodium Abundances in Nearby Disk Stars,

We present sodium abundances for a sample of nearby stars. All results have been derived from NLTE statistical equilibrium calculations. The influence of collisional interactions with electrons and hydrogen atoms is evaluated by comparison of the solar spectrum with very precise fits to the Na I line cores. The NLTE effects are more pronounced in metal-poor stars since the statistical equilibrium is dominated by collisions of which at least the electronic component is substantially reduced. The resulting influence on the determination of sodium abundances is in a direction opposite to that found previously for Mg and Al. The NLTE corrections are about −0.1 in thick-disk stars with [Fe/H] ∼−0.6. Our [Na/Fe] abundance ratios are about solar for thick- and thin-disk stars. The increase in [Na/Fe]asafunctionof[Fe/H] for metal-rich stars found by Edvardsson et al. (1993) is confirmed. Our results suggest that sodium yields increase with the metallicity, and quite large amounts of sodium may be produced by AGB stars. We find that [Na/Fe] ratios, together with either [Mg/Fe] ratio, kinematic data or stellar evolutionary ages, make possible the individual discrimination between thin- and thick-disk membership.

    Draft: Submitted to ApJ Supp. A Preprint typeset using LTEX style emulateapj v. 5/2/11 PRECISE RADIAL VELOCITIES OF 2046 NEARBY FGKM STARS AND 131 STANDARDS1 Carly Chubak2, Geoffrey W. Marcy2, Debra A. Fischer5, Andrew W. Howard2,3, Howard Isaacson2, John Asher Johnson4, Jason T. Wright6,7 (Received; Accepted) Draft: Submitted to ApJ Supp. ABSTRACT We present radial velocities with an accuracy of 0.1 km s−1 for 2046 stars of spectral type F,G,K, and M, based on ∼29000 spectra taken with the Keck I telescope. We also present 131 FGKM standard stars, all of which exhibit constant radial velocity for at least 10 years, with an RMS less than 0.03 km s−1. All velocities are measured relative to the solar system barycenter. Spectra of the Sun and of asteroids pin the zero-point of our velocities, yielding a velocity accuracy of 0.01 km s−1for G2V stars. This velocity zero-point agrees within 0.01 km s−1 with the zero-points carefully determined by Nidever et al. (2002) and Latham et al. (2002). For reference we compute the differences in velocity zero-points between our velocities and standard stars of the IAU, the Harvard-Smithsonian Center for Astrophysics, and l’Observatoire de Geneve, finding agreement with all of them at the level of 0.1 km s−1. But our radial velocities (and those of all other groups) contain no corrections for convective blueshift or gravitational redshifts (except for G2V stars), leaving them vulnerable to systematic errors of ∼0.2 km s−1 for K dwarfs and ∼0.3 km s−1 for M dwarfs due to subphotospheric convection, for which we offer velocity corrections.

  • Altair's Oblateness and Rotation Velocity

To first order, an ellipse may be fit to our interfero- metric diameter measurements, with major and minor axes of 2a =3.461 ± 0.038 milliarcseconds (mas) and 2b = 3.037 ± 0.069 mas, respectively, for a difference of 424 ± 79 microarcseconds (µas) between 2a and 2b, and with an axial ratio of a/b =1.140 ± 0.029. Assuming that the apparent oblateness of the photosphere is due to the star’s rapid rotation, a more rigorous evaluation of the observation data in the context of a rigidly rotating Roche model shows that an estimate of v sin i = 210 ± 13 km s−1 can be derived that is independent of spectroscopic techniques.

The Keck nuller was designed for the study of faint dust signatures associated with debris disks, but it also has a unique capability for studying the temperature and density distribution of denser disks found around young stellar objects. Interferometric observations of MWC 325 at K, L, and N encompass a factor of five in spectral range and thus, especially when spectrally dispersed within each band, enable characterization of the structure of the inner disk regions where planets form.

Current models of rotational evolution due to magnetic braking model all stars as single. However, these models may not be accurate in the rapidly rotating regime because they fail to consider the different evolution of stars in close or tidally synchronized binaries. Additionally, Kepler’s broad pixels introduce possible sources of contamination (period misattribution) from fainter stars near or collinear with the target, which could be contributing a fraction of the light but all of the variability. I present an ongoing pilot study on the extent of contamination and binarity among the rapidly rotating (P < 10 days) portion of the García et al.
