  • Dekany, I.; Minniti, D.; Majaess, Daniel J.; Zoccali, M.; Hajdu, G.; Alonso-Garcia, J.; Catelan, M.; Gieren, W.; Borissova, J. (American Astronomical Society, 2015-10-20)
    Solid insight into the physics of the inner Milky Way is key to understanding our Galaxy’s evolution, but extreme dust obscuration has historically hindered efforts to map the area along the Galactic mid-plane. New ...

  • Vanderburg, Andrew; Montet, Benjamin T.; Johnson, John Asher; Buchhave, Lars A.; Zeng, Li; Pepe, Francesco; Cameron, Andrew Collier; Latham, David W.; Molinari, Emilio; Udry, Stephane; Guenther, David B. (American Astronomical Society, 2015-02-10)
    We report the first planet discovery from the two-wheeled Kepler (K2) mission: HIP 116454 b. The host star HIP 116454 is a bright (V = 10.1, K = 8.0) K1 dwarf with high proper motion and a parallax-based distance of 55.2 ...

  • Miller, J. M.; Tomsick, J. A.; Bachetti, M.; Wilkins, D.; Boggs, S. E.; Christensen, F. E.; Craig, W. W.; Fabian, A. C.; Grefenstette, B. W.; Hailey, C. J. (American Astronomical Society, 2015-01-20)
    We report on an observation of the Galactic black hole candidate GRS 1739−278 during its 2014 outburst, obtained with NuSTAR. The source was captured at the peak of a rising “low/hard” state, at a flux of ~0.3 Crab. A broad, ...

  • Pablo, Herbert; Richardson, Noel D.; Moffat, Anthony F. J.; Corcoran, Michael; Shenar, Tomer; Benvenuto, Omar; Fuller, Jim; Naze, Yael; Hoffman, Jennifer L.; Miroshnichenko, Anatoly; Guenther, David B. (American Astronomical Society, 2015-08-20)
    We report on both high-precision photometry from the Microvariability and Oscillations of Stars (MOST) space telescope and ground-based spectroscopy of the triple system [delta] Ori A, consisting of a binary O9.5II+early-B ...

  • LaMassa, Stephanie M.; Cales, Sabrina; Moran, Edward C.; Myers, Adam D.; Richards, Gordon T.; Eracleous, Michael; Heckman, Timothy M.; Gallo, Luigi C.; Urry, C. Megan (American Astronomical Society, 2015-02-20)
    SDSS J015957.64+003310.5 is an X-ray selected, z = 0.31 active galactic nucleus (AGN) from the Stripe 82X survey that transitioned from a Type 1 quasar to a Type 1.9 AGN between 2000 and 2010. This is the most distant AGN, ...

  • Kirk, Helen; Klassen, Mikhail; Pudritz, Ralph; Pillsworth, Samantha (American Astronomical Society, 2015-04-01)
    We use numerical simulations of turbulent cluster-forming regions to study the nature of dense filamentary structures in star formation. Using four hydrodynamic and magnetohydrodynamic simulations chosen to match observations, ...

  • Geroux, Christopher M.; Deupree, Robert G. (Robert Gaston), 1946- (American Astronomical Society, 2015-02-10)
    Three-dimensional hydrodynamic simulations of full amplitude RR Lyrae stars have been computed for several models across the instability strip. The three-dimensional nature of the calculations allows convection to be treated ...

  • Foschini, L.; Berton, M.; Caccianiga, A.; Ciroi, S.; Cracco, V.; Peterson, B. M.; Angelakis, E.; Braito, V.; Fuhrmann, L.; Gallo, Luigi C. (EDP Sciences, 2015-03)
    We have conducted a multiwavelength survey of 42 radio loud narrow-line Seyfert 1 galaxies (RLNLS1s), selected by searching among all the known sources of this type and omitting those with steep radio spectra. We analyse ...

  • Kovtyukh, V. V.; Soubiran, C.; Luck, R. E.; Turner, David Gerald, 1945-; Belik, S. I.; Andrievsky, S. M.; Chekhonadskikh, F. A. (Oxford University Press, 2008)
    Accurate and homogeneous atmospheric parameters (T[subscript eff], log g, V[subscript t], [Fe/H]) are derived for 74 FGK non-variable supergiants from high-resolution, high signal-to-noise ratio, echelle spectra. Extremely ...

  • Berdnikov, Leonid N.; Turner, David Gerald, 1945- (American Astronomical Society, 2001-11)
    A total of 2097 photometric observations in the BVI[subscript c] system are presented for 117 Cepheids located in the southern hemisphere. The main purpose of the photometry is to provide new epochs of maximum brightness ...
