The uncertainty in water mass fraction of wet planets
Michael Lozovsky
Planets with masses between Earth and Neptune often have radii that imply the presence of volatiles, suggesting that water may be abundant in their interiors. However, directly obs…
On the Ordering of Exoplanet Systems
Michael Lozovsky, Hagai B. Perets
We present a comprehensive analysis of planetary radii ordering within multi-planet systems, namely their ordinal position with respect to their size in a given system, utilizing d…
About the loss of a primordial atmosphere of super-Earths by planetesimal impacts
Michael Lozovsky, Dina Prialnik, Morris Podolak
We consider planets composed of water ice and rock, located far from a central star. In an earlier study, computing the growth of planets by continuous accretion, we found that a l…
The Effect of Accretion Rate and Composition on the Structure of Ice-rich Super-Earths
Michael Lozovsky, Dina Prialnik, Morris Podolak
It is reasonable to assume that the structure of a planet and the interior distribution of its components are determined by its formation history. We thus follow the growth of a pl…
Why do more massive stars host larger planets?
Michael Lozovsky, Ravit Helled, Illaria Pascucci +3
It has been suggested that planetary radii increase with the stellar mass, for planets below 6 R and host below 1 M. In this study, we explore whether this infer…
A remnant planetary core in the hot-Neptune desert
David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91
The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…
Threshold radii of volatile-rich planets
Michael Lozovsky, Ravit Helled, Caroline Dorn +1
Constraining the planetary composition is essential for exoplanetary characterization. In this paper, we use a statistical analysis to determine the characteristic maximum (thresho…
Jupiter's formation and its primordial internal structure
Michael Lozovsky, Ravit Helled, Eric D. Rosenberg +1
The composition of Jupiter and the primordial distribution of the heavy elements are determined by its formation history. As a result, in order to constrain the primordial internal…
A possible correlation between planetary radius and orbital period for small planets
Ravit Helled, Michael Lozovsky, Shay Zucker
We suggest the existence of a correlation between the planetary radius and orbital period for planets with radii smaller than 4 R_Earth. Using the Kepler data, we find a correlatio…
