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...

Solving Linearized Equations of the $N$-body Problem Using the Lie-integration Method (2007)

Pal, Andras, Suli, Aron

Several integration schemes exits to solve the equations of motion of the $N$-body problem. The Lie-integration method is based on the idea to solve ordinary differential equations with Lie-series....

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...

Astrometry in Wide-field Surveys (2006)

Pal, Andras, Bakos, Gaspar

We present a robust and fast algorithm for performing astrometry and source cross-identification on two dimensional point lists, such as between a catalogue and an astronomical image, or between two...

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...
