Celestial bodies with a mass of M ~ 10 M_Jup have been found orbiting nearby stars. It is unknown whether these objects formed like gas-giant planets through core accretion or like stars through gravitational instability. I show that objects with M ~ 10 M_Jup do not share this property. This transition is coincident with a minimum in the occurrence rate of such objects, suggesting that the maximum mass of a celestial body formed through core accretion like a planet is less than 10 M_Jup…

The results show that planets can reside in much more massive stellar systems than what would be expected from extrapolation of previous results.
Multiple Populations of Extrasolar Gas Giants
There are two planetary formation scenarios: core accretion and gravitational disk instability. Based on the fact that gaseous objects are preferentially observed around metal-rich host stars, most
The paradox of youth for ALMA planet candidates
Recent ALMA observations indicate that the majority of bright protoplanetary discs show signatures of young moderately massive planets. I show that this result is paradoxical. The planets should
A high binary fraction for the most massive close-in giant planets and brown dwarf desert members
Stellar multiplicity is believed to influence planetary formation and evolution, although the precise nature and extent of this role remain ambiguous. We present a study aimed at testing the role
On the Mass Function, Multiplicity, and Origins of Wide-orbit Giant Planets
A major outstanding question regarding the formation of planetary systems is whether wide-orbit giant planets form differently than close-in giant planets. We aim to establish constraints on two key

Observations support the hypothesis that gas disk gravitational instability might explain the formation of massive or wide-orbit gas giant exoplanets. The situation with regard to Jupiter-mass

Observational evidence suggests that gas disk instability may be responsible for the formation of at least some gas giant exoplanets, particularly massive or distant gas giants. With regard to
Constraining the initial planetary population in the gravitational instability model
Direct imaging (DI) surveys suggest that gas giants beyond 20 au are rare around FGK stars. However, it is not clear what this means for the formation frequency of gravitational instability (GI)
Connecting substellar and stellar formation: the role of the host star’s metallicity
Context. Most of our current understanding of the planet formation mechanism is based on the planet metallicity correlation derived mostly from solar-type stars harbouring gas-giant planets. Aims. To
ALMA observations require slower Core Accretion runaway growth
Due to recent high-resolution ALMA observations, there is an accumulating evidence for presence of giant planets with masses from ${\sim } 0.01 \, {\rm {M}}_{\rm {J}}$ to a few $\, {\rm {M}}_{\rm


Formation of Giant Planets: Dependences on Core Accretion Rate and Grain Opacity
We have investigated the formation of gaseous envelopes of giant planets with wide ranges of parameters through quasi-static evolutionary simulations. In the nucleated instability model, rapid gas
Precise Radial Velocities of Giant Stars VII. Occurrence Rate of Giant Extrasolar Planets as a Function of Mass and Metallicity
(abridged) We have obtained precise radial velocities for a sample of 373 G and K type giants at Lick Observatory regularly over more than 12 years. Planets have been identified around 15 giant
Stellar Metallicity and the Formation of Extrasolar Gas Giant Planets
Spectroscopic searches for extrasolar planets are most successful when the target star has high metallicity, a trend that may be caused by observational selection effects, pollution by ingested
Final Masses of Giant Planets II: Jupiter Formation in a Gas-Depleted Disk
Firstly, we study the final masses of giant planets growing in protoplanetary disks through capture of disk gas, by employing an empirical formula for the gas capture rate and a shallow disk gap
Searching for chemical signatures of brown dwarf formation
Recent studies have shown that close-in brown dwarfs in the mass range 35-55 M$_{\rm Jup}$ are almost depleted as companions to stars, suggesting that objects with masses above and below this gap
The SOPHIE search for northern extrasolar planets - IX. Populating the brown dwarf desert
Radial velocity planet search surveys of nearby solar-type stars have shown a strong scarcity of brown dwarf companions within similar to 5 AU. There is presently no comprehensive explanation for
Observational evidence for two distinct giant planet populations
Analysis of the statistical properties of exoplanets, together with those of their host stars, are providing a unique view into the process of planet formation and evolution. In this paper we explore

Chemical abundances of stars with brown-dwarf companions
Context. It is well known that stars with giant planets are, on average, more metal-rich than stars without giant planets, whereas stars with detected low-mass planets do not require to be
