A Warm Massive Pair of Planets around TOI-1232 Revealed with Transit-timing Variations and Doppler Spectroscopy

The Astronomical Journal
TOI-1232 is a G dwarf star with a mass of $1.0{6}_{-0.06}^{+0.07}\,{M}_{\odot }$ , a radius of 1.07 ± 0.05 R _⊙ , and a slightly higher metallicity than solar of Fe/H = 0.18 ± 0.05. The star hosts a transiting warm Jovian-mass planet, TOI-1232 b, with an

Searching for Transit Timing Variations in Young Transiting Systems

The Astronomical Journal
The discovery of young (4 σ ), although differences in methodology make a totally fair comparison challenging. We show that spots have a weak-to-negligible impact on our results, and similarly cannot explain the higher TTV fraction.

Transit and secondary eclipse photometry in the near-infrared

, 2007
Near-infrared photometry of transiting extrasolar planets can be of great scientific value. It is however not straightforward to reach the necessary millimagnitude precision. Here we report on our attempts to observe transits and secondary eclipses of several extrasolar planets at 2.2 micron.

Quantifying the Effect of Short-timescale Stellar Activity Upon Transit Detection in M Dwarfs

The Astronomical Journal
M dwarf stars comprise 70%–80% of the galaxy's stars and host most of its rocky planets. They also differ from Sunlike stars in that they are “active” for billions of years or more: rotating quickly, flaring often, and emitting large amounts of UV and X ...
