Discovery of a young planetary mass companion to the nearby M dwarf VHS J125601.92-125723.9
- B. Gauza, V. S. Béjar, +5 authors G. Nowak
- Physics
- 4 May 2015
In a search for common proper motion companions using the VISTA Hemisphere Survey and 2MASS catalogs we have identified a very red (J-Ks=2.47 mag) late-L dwarf companion of a previously unrecognized… Expand
Substellar-mass companions to the K-dwarf BD +14 4559 and the K-giants HD 240210 and BD +20 2457

- Physics
- 9 June 2009
We present the discovery of substellar-mass companions to three stars by the ongoing Penn State-Torun Planet Search conducted with the 9.2 m Hobby-Eberly Telescope. The K2-dwarf, BD+14 4559, has a… Expand
The K2-ESPRINT Project I: Discovery of the Disintegrating Rocky Planet K2-22b with a Cometary Head and Leading Tail
- R. Sanchis-Ojeda, S. Rappaport, +28 authors L. Yu
- Physics
- 16 April 2015
We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hr: K2-22b. The highly variable transit depths, ranging from ~0% to 1.3%, are… Expand

Approximation properties for generalized q-Bernstein polynomials
- G. Nowak
- Mathematics
- 1 February 2009
In this paper, we introduce the generalized q-Bernstein polynomials based on the q-integers and we study approximation properties of these operators. In special case, we obtain Stancu operators or… Expand
Doppler Monitoring of five K2 Transiting Planetary Systems
In an effort to measure the masses of planets discovered by the NASA K2 mission, we have conducted precise Doppler observations of five stars with transiting planets. We present the results of a… Expand
Detection of sodium in the atmosphere of WASP-69b
- N. Casasayas-Barris, E. Pallé, G. Nowak, F. Yan, L. Nortmann, F. Murgas
- Physics
- 17 October 2017
Transit spectroscopy is one of the most commonly used methods to characterize exoplanets atmospheres. From the ground, these observations are very challenging due to the terrestrial atmosphere and… Expand
The K2-ESPRINT Project III: A Close-in Super-Earth around a Metal-rich Mid-M Dwarf
We validate a $R_p=2.32\pm 0.24R_\oplus$ planet on a close-in orbit ($P=2.260455\pm 0.000041$ days) around K2-28 (EPIC 206318379), a metal-rich M4-type dwarf in the Campaign 3 field of the K2… Expand
DISCOVERY OF TWO NEW THERMALLY BLOATED LOW-MASS WHITE DWARFS AMONG THE KEPLER BINARIES
- S. Rappaport, L. Nelson, +5 authors A. Prša
- Physics
- 8 February 2015
We report the discovery of two new low-mass, thermally bloated, hot white dwarfs among the Kepler sample of eclipsing binaries. These are KIC 9164561 and KIC 10727668 with orbital periods of 1.2670… Expand
The GTC exoplanet transit spectroscopy survey - VI. Detection of sodium in WASP-52b’s cloudy atmosphere
- G. Chen, E. Pallé, L. Nortmann, F. Murgas, H. Parviainen, G. Nowak
- Physics
- 20 March 2017
We report the first detection of sodium absorption in the atmosphere of the hot Jupiter WASP-52b. We observed one transit of WASP-52b with the low-resolution Optical System for Imaging and… Expand
