چکیده

We discuss the difficulties faced by the conventional theory of planet formation, which involves aggregation of microscopic dust particles. We describe an alternative hypothesis, termed concurrent collapse, in which planets form by gravitational collapse at the same time as the star about which they orbit. This mechanism avoids theoretical difficulties associated with the conventional model and suggests satisfying explanations for various poorly understood phenomena. We introduce new explanations for FU Orionis outbursts seen in young stars, the discovery of exoplanets with eccentric orbits and the existence of small rocky objects such as chondrules in the solar system.

After reviewing the difficulties faced by the conventional theory of planet formation (based upon the aggregation of microscopic dust particles), we describe an alternative hypothesis. We propose that planets form by gravitational collapse at the same time as the star about which they orbit. This concurrent collapse hypothesis avoids theoretical difficulties associated with the conventional mod...

The Moon Meets All Requirements of the IAU Definition for “Planet”

The Earth-Moon system has often been characterized as having some characteristics of a “double planet” system. It is demonstrated that while the orbital barycenter of the Earth-Moon pair lies inside the radius of the Earth, the Moon does meet all three requirements of the IAU definition for “planet” and therefore the Moon can correctly be identified as the Solar System’s 9 planet. In order to a...

Planet formation is unlikely in equal mass binary systems with a ∼ 50 AU

We show that planet formation via both gravitational collapse and core accretion is unlikely to occur in equal mass binary systems with moderate (∼ 50 AU) semimajor axes. Internal thermal energy generation in the disks is sufficient to heat the gas everywhere so that spiral structures quickly decay rather than grow or fragment. This same heating will inhibit dust coagulation because the tempera...

On the history and future of cosmic planet formation

We combine constraints on galaxy formation histories with planet formation models, yielding the Earth-like and giant planet formation histories of the Milky Way and the Universe as a whole. In the Hubble volume (1013 Mpc3), we expect there to be ∼1020 Earth-like and ∼1020 giant planets; our own galaxy is expected to host ∼109 and ∼1010 Earth-like and giant planets, respectively. Proposed metall...

Standing on the shoulders of giants Trojan Earths and vortex trapping in low mass self-gravitating protoplanetary disks of gas and solids

Context. Centimeter and meter-sized solid particles in protoplanetary disks are trapped within long-lived, high-pressure regions, creating opportunities for collapse into planetesimals and planetary embryos. Aims. We aim to study the effect of the high-pressure regions generated in the gaseous disks by a giant planet perturber. These regions consist of gas retained in tadpole orbits around the ...
