A Possible Correlation between Mass Ratio and Period Ratio in Multiple Planetary Systems
Tsevi Mazeh, Shay Zucker
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 eff…
Cross-Correlation and Maximum Likelihood Analysis: A New Approach to Combine Cross-Correlation Functions
Shay Zucker
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 ca…
A Statistical Analysis of The Extrasolar Planets and The Low-Mass Secondaries
Tsevi Mazeh, Shay Zucker
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 suggesti…
Analysis of the Hipparcos Observations of the Extrasolar Planets and the Brown-Dwarf Candidates
Shay Zucker, Tsevi Mazeh
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 measur…
Derivation of the Mass Distribution of Extrasolar Planets with MAXLIMA - a Maximum Likelihood Algorithm
Shay Zucker, Tsevi Mazeh
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 th…
On the Statistical Significance of the Hipparcos Astrometric Orbit of rho Coronae Borealis
Shay Zucker, Tsevi Mazeh
Recently Gatewood, Han & Black presented an analysis of the Hipparcos stellar positions and their own ground-based measurements of rho CrB, suggesting an astrometric orbit of 1.5 m…
