TL;DR: In this article, the authors reported the discovery of an extrasolar planet, KMT-2015-1b, that was detected using the microlensing technique, which was observed by KMTNet survey that has commenced in 2015.

TL;DR: In this paper, the authors presented the observational results of 1SWASP J093010.78+533859.5, for which the doubly eclipsing feature had been detected previously from the SuperWASP photometric archive.

TL;DR: In this paper, the authors presented UBVI absolute and V-band time-series CCD photometric results for the intermediate-age open cluster NGC 2539. From the empirical zero-age main sequence and theoretical isochrone fitting in color-color and color-magnitude diagrams, they estimated the physical parameters of this cluster as follows: the color excess of E(B − V) = 0.06 ± 0.03, the distance modulus of (V − MV)0 = 10.2 ± 1.1 and the age of log

TL;DR: In this paper , the authors investigate the data collected by the high-cadence microlensing surveys during the 2022 season in search for planetary signals appearing in the light curves of micro-lensing events and find that the anomaly is better explained by the planetary model than the binary-source model.

TL;DR: In this paper, the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001 were presented, where they used a small grid of models to constrain the main mode (f_1) which most likely represents the radial fundamental pulsation.
