A search for transits of GJ 581\lowercase{e} and characterization of the host star variability using MOST space telescope photometry [PDF]
, 2012 The GJ 581 system has been amply studied since its discovery in 2005: the number of known planets in the system has increased and their orbital parameters are among the most precisely determined for radial velocity detected exoplanets.

Exoplanet transits with next-generation radio telescopes [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Nearly everything we know about extrasolar planets to date comes from optical astronomy. While exoplanetary aurorae are predicted to be bright at low radio frequencies (< 1 GHz), we consider the effect of an exoplanet transit on radio emission from the ...

Eclipsing binary and white dwarf features associated with K2 target EPIC251248385 [PDF]
, 2019 White dwarfs, remnants of Sun-like stars which have completed their evolution, are one of the most common types of stars in space. Despite this, very few white dwarfs have been observed in transiting or eclipsing systems, and only two planetary systems ...

The Astrophysical Journal, 2023 We present the first analysis of JWST near-infrared spectroscopy of stellar flares from TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6–2.8 μ m with the Near Infrared Imager and Slitless Spectrograph and 0.6–3.5 μ m ...

Transit Lightcurve Signatures of Artificial Objects [PDF]
, 2005 The forthcoming space missions, able to detect Earth-like planets by the transit method, will a fortiori also be able to detect the transit of artificial planet-size objects.

A Theory of Exoplanet Transits with Light Scattering [PDF]
, 2017 Exoplanet transit spectroscopy enables the characterization of distant worlds, and will yield key results for NASA's James Webb Space Telescope.

Efficient analysis in planet transit surveys [PDF]
, 2005 With the growing number of projects dedicated to the search for extrasolar planets via transits, there is a need to develop fast, automatic, robust methods with a statistical background in order to efficiently do the analysis.

No Conclusive Evidence for Transits of Proxima b in MOST Photometry [PDF]
, 2016 The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days.

Gray transits of WD 1145+017 over the visible band [PDF]
, 2016 We have observed several relatively deep transits of the white dwarf WD 1145+017 with the GTC over the wavelength range 480 nm to 920 nm. The observations covered approximately one hour on 2016 Jan 18 and two hours on 2016 Jan 20.

The Astrophysical Journal, 2023 For the majority of short-period exoplanets transiting massive stars with radiative envelopes, the spin angular momentum of the host star is greater than the planetary orbital angular momentum.
