HAT-P-11b: A super-neptune planet transiting a bright K star in the kepler field
We report on the discovery of HAT-P-11b, the smallest radius transiting extrasolar planet (TEP) discovered from the ground, and the first hot Neptune discovered to date by transit searches. HAT-P-11bExpand
A Photometric Variability Survey of Field K and M Dwarf Stars with HATNet
Using light curves from the HATNet survey for transiting extrasolar planets we investigate the optical broadband photometric variability of a sample of 27, 560 field K and M dwarfs selected by colorExpand
Frequent Flaring in the TRAPPIST-1 System-Unsuited for Life?
We analyze the K2 light curve of the TRAPPIST-1 system. The Fourier analysis of the data suggests P rot = 3.295 ± 0.003 days. The light curve shows several flares, of which we analyzed 42 events withExpand
HAT-P-12b: A LOW-DENSITY SUB-SATURN MASS PLANET TRANSITING A METAL-POOR K DWARF
We report on the discovery of HAT-P-12b, a transiting extrasolar planet orbiting the moderately bright V ≈ 12.8 K4 dwarf GSC 03033 – 00706, with a period P = 3.2130598 ± 0.0000021 d, transit epochExpand
The outburst and nature of two young eruptive stars in the North America/Pelican Nebula Complex
Context. In August 2010, the sudden optical brightening of two young stellar objects, HBC 722 and VSX J205126.1+440523, located in the North America/Pelican Nebula Complex, was announced. EarlyExpand
Refined stellar, orbital and planetary parameters of the eccentric HAT‐P‐2 planetary system
We present refined parameters for the extrasolar planetary system HAT-P-2 (also known as HD 147506), based on new radial velocity and photometric data. HAT-P-2b is a transiting extrasolar planet thatExpand
Spin–orbit resonance, transit duration variation and possible secular perturbations in KOI‐13
KOI-13 is the first known transiting system exhibiting light-curve distortions due to gravity darkening of the rapidly rotating host star. In this Letter, we analyse publicly available Kepler Q2–Q3Expand
“TNOs are Cool”: A survey of the trans-Neptunian region - X. Analysis of classical Kuiper belt objects from Herschel and Spitzer observations
Context. The Kuiper belt is formed of planetesimals which failed to grow to planets and its dynamical structure has been affected by Neptune. The classical Kuiper belt contains objects both from aExpand
Tools for discovering and characterizing extrasolar planets
Among the group of extrasolar planets, transiting planets provide a great opportunity to obtain direct measurements for the basic physical properties, such as mass and radius of these objects. TheseExpand
Long-term transit timing monitoring and refined light curve parameters of HAT-P-13b
We present 10 new transit light curves of the transiting hot Jupiter HAT-P-13b, obtained during two observational seasons by three different telescopes. When combined with 12 previously publishedExpand
