The New Horizons (NH) flyby of the Pluto–Charon binary planet and its system of four small
surrounding satellites in mid-2015 revolutionized our knowledge of this distant planet and its …

Recent advances in interplanetary dust modelling provide much improved estimates of the
fluxes of cosmic dust particles into planetary (and lunar) atmospheres throughout the solar …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

The observed mass–radius relationship of low-mass planets informs our understanding of
their composition and evolution. Recent discoveries of low-mass, large-radius objects (" …

The Alice instrument on NASA's New Horizons spacecraft observed an ultraviolet solar
occultation by Pluto's atmosphere on 2015 July 14. The transmission vs. altitude was …

Most chemistry and cloud formation models for planetary atmospheres adopt a one-
dimensional (1D) diffusion approach to approximate the global-mean vertical tracer …

Disequilibrium chemistry due to vertical mixing in the atmospheres of many brown dwarfs
and giant exoplanets is well established. Atmosphere models for these objects typically …

Pluto's atmospheric haze settles out rapidly compared with geological timescales. It needs to
be accounted for as a surface material, distinct from Pluto's icy bedrock and from the volatile …

Pluto's atmosphere is cold and hazy,,. Recent observations have shown it to be much colder
than predicted theoretically, suggesting an unknown cooling mechanism. Atmospheric gas …
