Photometric follow-up of the transiting planet WASP-1b (2006)
Shporer, Avi, Tamuz, Omer, Zucker, Shay, Mazeh, Tsevi
We report on photometric follow-up of the recently discovered transiting planet WASP-1b. We observed two transits with the Wise Observatory 1m telescope, and used a variant of the EBOP code together...
Spectroscopic Binary Mass Determination using Relativity (2006)
High-precision radial-velocity techniques, which enabled the detection of extrasolar planets are now sensitive to relativistic effects in the data of spectroscopic binary stars (SBs). We show how...
The effect of red noise on planetary transit detection (2006)
Pont, Frederic, Zucker, Shay, Queloz, Didier
Since the discovery of short-period exoplanets a decade ago, photometric surveys have been recognized as a feasible method to detect transiting hot Jupiters. Many transit surveys are now under way,...
TIRAVEL - Template Independent RAdial VELocity measurement (2006)
We propose a new approach to measure differential radial velocities, mainly for single-lined spectroscopic binaries. The proposed procedure - TIRAVEL (Template Independent RAdial VELocities) - does...

Probing Post-Newtonian Gravity near the Galactic Black Hole with Stellar Doppler Measurements (2005)
Zucker, Shay, Alexander, Tal, Gillessen, Stefan, Eisenhauer, Frank, Genzel, Reinhard
Stars closely approaching the massive black hole in the center of the Galaxy provide a unique opportunity to probe post-Newtonian physics in a yet unexplored regime of celestial mechanics. Recent...
Correcting systematic effects in a large set of photometric lightcurves (2005)
Tamuz, Omer, Mazeh, Tsevi, Zucker, Shay
We suggest a new algorithm to remove systematic effects in a large set of lightcurves obtained by a photometric survey. The algorithm can remove systematic effects, like the ones associated with...

An intriguing correlation between the masses and periods of the transiting planets (2004)
Mazeh, Tsevi, Zucker, Shay, Pont, Frederic
We point out an intriguing relation between the masses of the transiting planets and their orbital periods. For the six currently known transiting planets, the data are consistent with a decreasing...
A Possible Correlation between Mass Ratio and Period Ratio in Multiple Planetary Systems (2003)
We report on a possible correlation between the mass ratio and period ratio of pairs of adjacent planets in extra-solar planetary systems. Monte-Carlo simulations show that the effect is significant...
This paper presents a new approach to combine cross-correlation functions. The combination is based on a maximum-likelihood approach and uses a non-linear combination scheme. It can be effective for...

A Statistical Analysis of The Extrasolar Planets and The Low-Mass Secondaries (2002)
We show that the astrometric Hipparcos data of the stars hosting planet candidates are not accurate enough to yield statistically significant orbits. Therefore, the recent suggestion, based on the...
We analyzed the Hipparcos astrometric observations of 47 stars that were discovered to harbor giant planets and 14 stars with brown-dwarf secondary candidates. The Hipparcos measurements were used...
We construct a maximum-likelihood algorithm - MAXLIMA, to derive the mass distribution of the extrasolar planets when only the minimum masses are observed. The algorithm derives the distribution by...
