Lessons from the apparent peculiar nature of the star <span>TYC</span> 6544‐3483‐1 Open
We report a radio and optical study of the star TYC 6544‐3483‐1 originally selected as a follow‐up target in the course of our efforts to cross‐identify Galactic high‐energy sources. The star by itself finally turned out to be a very ordin…

Robotilter: An automated lens/CCD alignment system for the Evryscope Open
Camera lenses are increasingly used in wide-field astronomical surveys due to their high performance, wide field-of-view (FOV) unreachable from traditional telescope optics, and modest cost. The machining and assembly tolerances for commer…

TFAW survey II: 6 Newly Validated Planets and 13 Planet Candidates from K2 Open
Searching for Earth-sized planets in data from Kepler's extended mission (K2) is a niche that still remains to be fully exploited. The TFAW survey is an ongoing project that aims to re-analyze all light curves in K2 C1-C8 and C12-C18 campa…

Optical microflares in LS I +61 303 and the search for their multiwavelength counterpart Open
Context. Stellar sources of gamma rays are one of the front lines in modern astrophysics whose understanding can benefit from observational tools not originally designed for their study. Aims. We take advantage of the high precision photom…

TFAW K2 survey: an insight into a few hundreds of new Earth-sized planetary candidates Open
Kepler's extended mission (K2) Earth-sized planetary legacy is a niche that still remains to be fully exploited. We reanalyzed all light curves in K2 C1-C8, C12-C18 campaigns with a wavelet-based detrending method TFAW developed by our tea…

tfaw survey – I. Wavelet-based denoising of K2 light curves. Discovery and validation of two new Earth-sized planets in K2 campaign 1 Open
The wavelet-based detrending and denoising method tfaw is applied for the first time to EVEREST 2.0-corrected light curves to further improve the photometric precision of almost all K2 observing campaigns (C1–C8, C12–C18). The performance …

EvryFlare. II. Rotation Periods of the Cool Flare Stars in TESS across Half the Southern Sky Open
We measure rotation periods and sinusoidal amplitudes in Evryscope light curves for 122 two-minute K5–M4 TESS targets selected for strong flaring. The Evryscope array of telescopes has observed all bright nearby stars in the south, produci…

EvryFlare II: Rotation Periods and Starspot Coverage of Cool Active Stars Throughout the Spin-down Process Open
We measure photometric rotation periods and starspot amplitudes in Evryscope light curves for 113 cool stars selected to have strong flaring. The Evryscope array of small telescopes has observed all bright nearby stars in the Southern sky,…

TFAW: Wavelet-based signal reconstruction to reduce photometric noise in time-domain surveys Open
Context. There have been many efforts to correct systematic effects in astronomical light curves to improve the detection and characterization of planetary transits and astrophysical variability. Algorithms such as the trend filtering algo…
