TOI-1408: the limb darkening models, photometric and Doppler noises, and the exoplanetary system
Roman V. Baluev
We perform a self-consistent analysis of Doppler and photometric TESS and ground-based transit observations available for TOI-1408, known to host a system with two planets orbiting…
Cleaning WASP-33 b transits from the host star photometric variability: analysis of TESS data from two sectors
Roman V. Baluev, Eugene N. Sokov
Based on TESS observations of a Scuti variable WASP-33 obtained in 2019 and 2022, we thoroughly investigate the power spectrum of this target photometric flux and construct a s…
Doppler confirmation of TESS planet candidate TOI1408.01: grazing transit and likely eccentric orbit
G. A. Galazutdinov, R. V. Baluev, G. Valyavin +16
We report an independent Doppler confirmation of the TESS planet candidate orbiting an F-type main sequence star TOI-1408 located 140 pc away. We present a set of radial velocities…
Comparing the frequentist and Bayesian periodic signal detection: rates of statistical mistakes and sensitivity to priors
Roman V. Baluev
We perform extensive Monte Carlo simulations to systematically compare the frequentist and Bayesian treatments of the Lomb--Scargle periodogram. The goal is to investigate whether…
The impact of photospheric brightness field on exoplanetary transit timings and the TTV excess of HD 189733 b
Roman V. Baluev
We consider the issue of excessive TTV noise observed for the exoplanet HD 189733 b. Trying to explain it through the host star photospheric activity, we model the stellar surface…
Massive search of spot- and facula-crossing events in 1598 exoplanetary transit lightcurves
R. V. Baluev, E. N. Sokov, I. A. Sokova +40
We developed a dedicated statistical test for a massive detection of spot- and facula-crossing anomalies in multiple exoplanetary transit lightcurves, based on the frequentist -…
