We present the mass–density relationship (log M − log ρ) for objects with masses ranging from planets (M ≈ 0.01 MJup) to stars (M > 0.08 M⊙). This relationship shows three distinct regions separated by a change in slope in the log M − log ρ plane. In particular, objects with masses in the range 0.3 MJup–60 MJup follow a tight linear relationship with no distinguishing feature to separate the low-mass end (giant planets) from the high-mass end (brown dwarfs). We propose a new definition of giant… 

Two empirical regimes of the planetary mass-radius relation

Today, with the large number of detected exoplanets and improved measurements, we can reach the next step of planetary characterization. Classifying different populations of planets is not only

Evidence of an Upper Bound on the Masses of Planets and Its Implications for Giant Planet Formation

Celestial bodies with a mass of 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

K2-106, a system containing a metal-rich planet and a planet of lower density

Planets in the mass range from 2 to 15 M_Earth are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities, structure, and

The Origin of the Heavy-element Content Trend in Giant Planets via Core Accretion

We explore the origin of the trend of heavy elements in observed massive exoplanets. Coupling of better measurements of the mass (Mp) and radius of exoplanets with planet structure models enables

A Sanity Check for Planets around Evolved Stars

We present the radius–period plot for exoplanet candidates around giant stars. The diagram contains two distinct regions. While planets of giants with radii smaller than 21 R ⊙ exhibit a wide range

Planet formation around M dwarfs via disc instability

Context. Around 30 per cent of the observed exoplanets that orbit M dwarf stars are gas giants that are more massive than Jupiter. These planets are prime candidates for formation by disc

Close binaries suppress the formation of circumstellar (S-type) planets and therefore significantly bias the inferred planet occurrence rates and statistical trends. After compiling various radial

Absolute densities in exoplanetary systems: photodynamical modelling of Kepler-138

In favourable conditions, the density of transiting planets in multiple systems can be determined from photometry data alone. Dynamical information can be extracted from light curves, providing

The TOI-763 system: sub-Neptunes orbiting a Sun-like star

We report the discovery of a planetary system orbiting TOI-763(aka CD-39 7945), a V = 10.2, high proper motion G-type dwarf star that was photometrically monitored by the TESS space mission in

Minimum Orbital Periods of H-rich Bodies

In this work we derive the minimum allowed orbital periods of H-rich bodies ranging in mass from Saturn’s mass to 1 M ⊙, emphasizing gas giants and brown dwarfs (BDs) over the range 0.0003–0.074 M ⊙.

Discovery of two young brown dwarfs in an eclipsing binary system

This work reports the discovery of a brown-dwarf eclipsing binary system, in the Orion Nebula star-forming region, from which direct measurements of mass and radius establish both objects as brown dwarfs, and finds that the less-massive brown dwarf is the hotter of the pair.

Abstract There has been considerable progress in our understanding of how massive stars form but still much confusion as to why they form. Recent work from several sources has shown that the
