The Spitzer search for the transits of HARPS low-mass planets [PDF]

, 2010
Radial velocity, microlensing and transit surveys have revealed the existence of a large population of low-mass planets in our Galaxy, the so-called ‘Super-Earths’ and ‘Neptunes’.

Model Checking Branching Properties on Petri Nets with Transits [PDF]

, 2020
To model check concurrent systems, it is convenient to distinguish between the data flow and the control. Correctness is specified on the level of data flow whereas the system is configured on the level of control.

TESS Spots a Super-puff: The Remarkably Low Density of TOI-1420b

The Astronomical Journal, 2023
We present the discovery of TOI-1420b, an exceptionally low-density ( ρ = 0.08 ± 0.02 g cm ^−3 ) transiting planet in a P = 6.96 days orbit around a late G-dwarf star.

Computing Transiting Exoplanet Parameters with 1D Convolutional Neural Networks

Axioms
The transit method allows the detection and characterization of planetary systems by analyzing stellar light curves. Convolutional neural networks appear to offer a viable solution for automating these analyses.

Transit timing, depth, and duration variation in exoplanet TrES-2?

EPJ Web of Conferences, 2011
We report on our ongoing search for timing, duration, and depth variations in the exoplanet TrES-2. In Raetz et al. (2009) we already presented ten different transits obtained at the University Observatory Jena.

Exoplanet Nodal Precession Induced by Rapidly Rotating Stars: Impacts on Transit Probabilities and Biases

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.

The fundamentals of Lyman-alpha exoplanet transits

, 2022
Lyman-$\alpha$ transits have been detected from several nearby exoplanets and are one of our best insights into the atmospheric escape process. However, due to ISM absorption, we typically only observe the transit signature in the blue-wing, making them ...

Rare exoplanet transits observed from Antarctica [PDF]

, 2021
Of the 870+ southern planetary candidates from TESS currently awaiting confirmation, roughly 10% have transit durations longer than five hours; over a third of these also have orbital periods longer than 20 days.

High Energy Exoplanet Transits

, 2016
X-ray and ultraviolet transits of exoplanets allow us to probe the atmospheres of these worlds. High energy transits have been shown to be deeper but also more variable than in the optical.
