M-dwarf stars—hydrogen-burning stars that are smaller than 60 per cent of the size of the Sun—are the most common class of star in our Galaxy and outnumber Sun-like stars by a ratio of 12:1. Recent results have shown that M dwarfs host Earth-sized planets in great numbers: the average number of M-dwarf planets that are between 0.5 to 1.5 times the size of Earth is at least 1.4 per star. The nearest such planets known to transit their star are 39 parsecs away, too distant for detailed follow-up… Expand
A temperate rocky super-Earth transiting a nearby cool star
TLDR
Observations of LHS 1140b, a planet with a radius of 1.4 Earth radii transiting a small, cool star (L HS 1140) 12 parsecs away, measure the mass of the planet to be 6.6 times that of Earth, consistent with a rocky bulk composition, and place an upper limit on the orbital eccentricity. Expand
Astronomy: A small star with an Earth-like planet
TLDR
Observations of GJ 1132b, a 1.2 Earth radius planet transiting a small star only 12 parsecs away, yield a density consistent with an Earth-like rock/iron composition. Expand
Diverse outcomes of planet formation and composition around low-mass stars and brown dwarfs
The detection of Earth-size exoplanets around low-mass stars –in stars such as Proxima Centauri and TRAPPIST-1– provide an exceptional chance to improve our understanding of the formation ofExpand
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, andExpand
TWO SMALL PLANETS TRANSITING HD 3167
We report the discovery of two super-Earth-sized planets transiting the bright (V = 8.94, K = 7.07) nearby late G-dwarf HD 3167, using data collected by the K2 mission. The inner planet, HD 3167 b,Expand
Stellar and Planetary Parameters for K2's Late-type Dwarf Systems from C1 to C5
The NASA K2 mission uses photometry to find planets transiting stars of various types. M dwarfs are of high interest since they host more short-period planets than any other type of main-sequenceExpand
The Muscles Treasury Survey. I. Motivation and Overview
Ground- and space-based planet searches employing radial velocity techniques and transit photometry have detected thousands of planet-hosting stars in the Milky Way. With so many planets discovered,Expand
An Earth-sized exoplanet with a Mercury-like composition
Earth, Venus, Mars and some extrasolar terrestrial planets1 have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle2. At the inner frontierExpand

Context. Low mass stars are currently the best targets for searches for rocky planets in the habitable zone of their host star. Over the last 13 years, precise radial velocities measured with theExpand
Super-Earth masses sculpted by pebble isolation around stars of different masses
We develop a pebble-driven model to study the formation and evolution of planets around stars in the mass range of 0.08 and 1 solar mass. The growth and migration of a large number of individualExpand

An Earth-sized planet with an Earth-like density
TLDR
The planet Kepler-78b was discovered and found to have a radius of only 1.16, and the mass of this planet is 1.86 Earth masses, which implies a composition of iron and rock similar to that of the Earth. Expand
A rocky composition for an Earth-sized exoplanet
TLDR
Doppler spectroscopic measurements of the mass of the Earth-sized planet Kepler-78b are reported, which is similar to Earth’s, suggesting a composition of rock and iron. Expand
A super-Earth transiting a nearby low-mass star
TLDR
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet. Expand
THE OCCURRENCE RATE OF SMALL PLANETS AROUND SMALL STARS

TLDR
Another violation of the orbit-composition pattern is reported: two planets orbiting the same star with orbital distances differing by only 10% and densities differing by a factor of 8, likely a rocky “super-Earth,” whereas the other is more akin to Neptune. Expand

Context. Planetary companions of a fixed mass induce reflex motions with a larger amplitude around lower-mass stars, which adds to making M dwarfs excellent targets for extra-solar planet searches.Expand
