A diagram to determine the evaporation status of extrasolar planets

, 2006
Aims.To describe the evaporation status of extrasolar planets, we consider an energy diagram in which the potential energy of the planets is plotted versus the energy received by the upper atmosphere.

Detecting extrasolar planets with sparse aperture masking

, 2016
Extrasolar planets are directly detected most easily when they are young and can have contrasts only a few hundred times fainter than their host stars at near- and mid- infrared wavelengths.

Properties of transiting extrasolar planets [PDF]

, 2011
A growing number of extrasolar planets have been detected using transit photometry, and these systems are presently important, in that these planets have strongly constrained parameters, particularly their radii, and this combined with the masses can ...

Direct imaging of massive extrasolar planets

, 2010
The direct detection of an extrasolar planet can provide accurate measurements of its orbit, mass and composition, greatly improving our understanding of how planets form and evolve. Recent advances in ground-based and space-based imaging techniques have

Searching for GEMS: TOI-5688 A b, a Low-density Giant Orbiting a High-metallicity Early M-dwarf

The Astronomical Journal
We present the discovery of a low-density planet orbiting the high-metallicity early M-dwarf TOI-5688 A b. This planet was characterized as part of the search for transiting giant planets ( R  ≳ 8 R _⊕ ) through the Searching for Giant Exoplanets around ...
