Abstract We present an analytic model for the interaction between planetary atmospheres and stellar winds from main sequence M stars, with the purpose of obtaining a quick test-model that estimates the timescale for total atmospheric mass loss due to this interaction. Planets in the habitable zone of M dwarfs may be tidally locked and may have weak magnetic fields, because of this we consider the extreme case of planets with no magnetic field. The model gives the planetary atmosphere mass loss… Expand

Monte Carlo Simulations of Atmospheric Loss by Stellar Winds from Exoplanets
Hot Jupiters are a class of extra-solar planets. Massive gas giants on the same size scale as Jupiter, they orbit their host stars closely. This proximity results in large stellar winds capable ofExpand
Effects of M dwarf magnetic fields on potentially habitable planets
We investigate the e ect of the magnetic fields of M dwarf (dM) stars on potentially habitable Earth-like planets. These fields can reduce the size of planetary magnetospheres to such an extent thatExpand
Mass, energy, and momentum capture from stellar winds by magnetized and unmagnetized planets: implications for atmospheric erosion and habitability
The extent to which a magnetosphere protects its planetary atmosphere from stellar wind ablation depends upon how well it prevents energy and momentum exchange with the atmosphere and how well itExpand
Habitable Zones of Post-Main Sequence Stars
Once a star leaves the main sequence and becomes a red giant, its Habitable Zone (HZ) moves outward, promoting detectable habitable conditions at larger orbital distances. We use a one-dimensionalExpand
Exoplanets as probes of the winds of host stars: the case of the M dwarf GJ 436
Winds of cool dwarfs are difficult to observe, with only a few M dwarfs presenting observationally-derived mass-loss rates (Mdot), which span several orders of magnitude. Close-in exoplanets areExpand
Powerful winds from low‐mass stars: V374 Peg
The M dwarf V374 Peg (M4) is believed to lie near the theoretical mass threshold for fully convective interiors. Its rapid rotation (P= 0.44 d) along with its intense magnetic field point towardsExpand
The Stellar Activity of TRAPPIST-1 and Consequences for the Planetary Atmospheres
The signatures of planets hosted by M dwarfs are more readily detected with transit photometry and radial velocity methods than those of planets around larger stars. Recently, transit photometry wasExpand
Constraining the Angular Momentum-loss Rates of the Sun and Other Sun-like Stars
1st Supervisor: Prof. Sean P. Matt 2nd Supervisor: Prof. Matthew Browning Stellar rotation, convection, and magnetism are intricately linked in low-mass stars like the Sun. In their outer convectiveExpand
The effects of stellar winds on the magnetospheres and potential habitability of exoplanets
Context. The principle definition of habitability for exoplanets is whether they can sustain liquid water on their surfaces, i.e. that they orbit within the habitable zone. However, the planet’sExpand
Constraining the Radiation and Plasma Environment of the Kepler Circumbinary Habitable Zone Planets
The discovery of many planets using the Kepler telescope includes ten planets orbiting eight binary stars. Three binaries, Kepler-16, Kepler-47, and Kepler-453, have at least one planet in theExpand


Theoretical mass loss rates of cool main-sequence stars
Context. The stellar mass loss rate is important for the rotational evolution of a star and for its interaction with the circumstellar environment. The analysis of astrospheric absorption featuresExpand
Measured Mass‐Loss Rates of Solar‐like Stars as a Function of Age and Activity
Collisions between the winds of solar-like stars and the local interstellar medium result in a population of hot hydrogen gas surrounding these stars. Absorption from this hot H i can be detected inExpand
Cosmic ray impact on extrasolar earth-like planets in close-in habitable zones.
It is shown that close-in extrasolar planets in the habitable zone of M stars are synchronously rotating with their host star because of the tidal interaction, and it is proposed that, depending on atmospheric pressure, biological systems on the surface of Earth-like Extrasolar planets at close- in orbital distances can be strongly influenced by secondary cosmic rays.

Kepler Planet-Detection Mission: Introduction and First Results
The planetary findings derived from the first six weeks of observations with the Kepler mission are summarized, which include the detection of five new exoplanets, which confirm the existence of planets with densities substantially lower than those predicted for gas giant planets. Expand
M stars as targets for terrestrial exoplanet searches and biosignature detection.
It is concluded that attempts at remote sensing of biosignatures and nonbiological markers from M star planets are important, not as tests of any quantitative theories or rational arguments, but instead because they offer an inspection of the residues from a Gyr-long biochemistry experiment in the presence of extreme environmental fluctuations.

We show that the flux distribution of a wind from a cool star differs considerably from what is predicted by the the- ory for mass loss from hot stars. The differences are caused byExpand
A reappraisal of the habitability of planets around M dwarf stars.
It is concluded that M dwarf stars may indeed be viable hosts for planets on which the origin and evolution of life can occur and it makes sense to include M dwarfs in programs that seek to find habitable worlds and evidence of life. Expand
Habitable zones around main sequence stars.
The results suggest that mid-to-early K stars should be considered along with G stars as optimal candidates in the search for extraterrestrial life. Expand
Observability of Stellar Winds from Late-Type Dwarfs via Charge Exchange X-Ray Emission
Despite the fact that the overwhelming majority of stars are of late spectral type (F-M) and lie on the main sequence, we know nothing about their stellar winds. Existing measurements of winds onlyExpand
Limits to Mass Outflows from Late-Type Dwarf Stars
We show that the mass-loss rates of active late-type dwarf stars must be significantly lower than recent estimates of up to ~5 × 10-10 M☉ yr-1, 4 orders of magnitude higher than that of the Sun.Expand
