Spitzer IRAC Secondary Eclipse Photometry of the Transiting Extrasolar Planet HAT-P-1b (2009)
Todorov, Kamen, Deming, Drake, Harrington, Jospeph, Stevenson, Kevin B., Bowman, William C., Nymeyer, Sarah, ...
We report Spitzer/IRAC photometry of the transiting giant exoplanet HAT-P-1b during its secondary eclipse. This planet lies near the postulated boundary between the pM and pL-class of hot Jupiters,...
HAT-P-9b: A Low Density Planet Transiting a Moderately Faint F star (2008)
Shporer, Avi, Bakos, Gaspar A., Bouchy, Francois, Pont, Frederic, Kovacs, Geza, Latham, Dave W., ...
We report the discovery of a planet transiting a moderately faint (V=12.3 mag) late F star, with an orbital period of 3.92289 +/- 0.00004 days. From the transit light curve and radial velocity...
Observability of the General Relativistic Precession of Periastra in Exoplanets (2008)
Jordan, Andres, Bakos, Gaspar A.
The general relativistic precession rate of periastra in close-in exoplanets can be orders of magnitude larger than the magnitude of the same effect for Mercury. The realization that some of the...
The Transit Light Curve Project. VII. The Not-So-Bloated Exoplanet HAT-P-1b (2007)
Winn, Joshua N., Holman, Matthew J., Bakos, Gaspar A., Pal, Andras, Johnson, John Asher, Williams, Peter K. G., ...
We present photometry of the G0 star HAT-P-1 during six transits of its close-in giant planet, and we refine the estimates of the system parameters. Relative to Jupiter's properties, HAT-P-1b is 1.20...
Spin-Orbit Alignment for the Eccentric Exoplanet HD 147506b (2007)
Winn, Joshua N., Johnson, John Asher, Peek, Kathryn M. G., Marcy, Geoffrey W., Bakos, Gaspar A., Enya, Keigo, ...
The short-period exoplanet HD 147506b (also known as HAT-P-2b) has an eccentric orbit, raising the possibility that it migrated through planet-planet scattering or Kozai oscillations accompanied by...
The Transit Light Curve (TLC) Project. I. Four Consecutive Transits of the Exoplanet XO-1b (2006)
Holman, Matthew J., Winn, Joshua N., Latham, David W., O'Donovan, Francis T., Charbonneau, David, Bakos, Gaspar A., ...
We present RIz photometry of four consecutive transits of the newly discovered exoplanet XO-1b. We improve upon the estimates of the transit parameters, finding the planetary radius to be R_P = 1.184...
A stellar companion in the HD 189733 system with a known transiting extrasolar planet (2006)
Bakos, Gaspar A., Pal, Andras, Latham, David W., Noyes, Robert W., Stefanik, Robert P.
We show that the very close-by (19 pc) K0 star HD 189733, already found to be orbited by a transiting giant planet, is the primary of a double-star system, with the secondary being a mid-M dwarf with...
Bakos, Gaspar A., Lazar, Jozsef, Papp, Istvan, Sari, Pal, Green, Elizabeth M.
Having been operational at Kitt Peak for more than a year, the prototype of the Hungarian Automated Telescope (HAT-1) has been used for all-sky variability search of the northern hemisphere. The...
Revised Coordinates and Proper Motions of the Stars in the Luyten Half-Second Catalogue (2002)
Bakos, Gaspar A., Sahu, Kailash C., Nemeth, Peter
We present refined coordinates and proper motion data for the high proper motion (HPM) stars in the Luyten Half-Second (LHS) catalogue. The positional uncertainty in the original Luyten catalogue is...
Discovery of the optical counterpart and early optical observations of GRB 990712 (2000)
Sahu, Kailash C., Vreeswijk, P. M., Bakos, Gaspar A., Menzies, John W., Bragaglia, Angela, Frontera, Filippo, ...
We present the discovery observations of the optical counterpart of the gamma-ray burst GRB 990712 taken 4.16 hr after the outburst and discuss its light curve observed in the V, R, and I bands...
Discovery of the optical counterpart and early optical observations of GRB 990712 (2000)
