Photometry of TIC 230386284, a Recently Found Bright Eclipsing Star in Draco.
PYATNYTSKYY M.
Abstract (from CDS):
The results of photometry are presented for the star TIC 230386284, of EA+UV type, recently found by the author while mining TESS data. The depth of primary eclipses in the Johnson V band derived from the authoris measurements was found to be significantly smaller (0.024 mag) compared to the TESS bandpass (0.11 mag). This was interpreted as a result of light contamination by an extremely close optical companion having a very different color. Estimation of the upper brightness limit of the variable out of eclipses and flares in the Johnson V band and brightness of the contaminating star was done; the contaminating star appeared to be brighter in V than the variable by at least 1.3 mag.
