“…separate out CB from other types of eclipsing binaries (mainly the Algol and Beta Lyrae types; for example in Rucinski 1997a,b;Selam 2004;Derekas et al 2007;Lee et al 2014;Muraveva et al 2014;Nedoroščík et al 2015;Yang et al 2020) or to classify CB against different types of variable stars in time-series surveys (for example, see Pojmanski 2002;Eyer & Blake 2005;Debosscher et al 2007;Hoffman et al 2009;Kim et al 2014;Masci et al 2014;Jayasinghe et al 2019). In this work, a 4 th -order Fourier expansion (Derekas et al 2007;Deb & Singh 2011;Dey et al 2015;Chen et al 2018) in the following form was adopted to fit the folded ZTF light curves for the CB listed in Table 4:…”

In this work, we aimed to derive the gri-band period-luminosity (PL) and period-luminosity-color (PLC) relations for late-type contact binaries, for the first time, located in the globular clusters, using the homogeneous light curves collected by the Zwicky Transient Factory (ZTF). We started with 79 contact binaries in 15 globular clusters, and retained 30 contact binaries in 10 globular clusters that have adequate number of data points in the ZTF light curves and unaffected by blending. Magnitudes at mean and maximum light of these contact binaries were determined using a fourth-order Fourier expansion, while extinction corrections were done using the Bayerstar2019 3D reddening map together with adopting the homogeneous distances to their host globular clusters. After removing early-type and "anomaly" contact binaries, our derived gri-band PL and period-Wesenheit (PW) relations exhibit a much larger dispersion with large errors on the fitted coefficients. Nevertheless, the gr-band PL and PW relations based on this small sample of contact binaries in globular clusters were consistent with those based on a larger sample of nearby contact binaries. Good agreements of the PL and PW relations suggested both samples of contact binaries in the local Solar neighborhood and in the distant globular clusters can be combined and used to derive and calibrate the PL, PW and PLC relations. The final derived gr-band PL, PW and PLC relations were much improved than those based on the limited sample of contact binaries in the globular clusters.

“…The latter category includes the ubercal photometric analysis (Schlafly et al 2012), the photoz analysis (Saglia et al 2012), and the QSO/RR Lyra search efforts (Hernitschek et al 2016). In addition, collaborations within the wider Pan-STARRS community have implemented a variety of science-level analyses of their own to support their science goals (e.g., M31 variable search; Lee et al 2012Lee et al , 2014. Figure 1 illustrates the many elements of the Pan-STARRS data analysis system.…”

“…Such high cadence data not only allowed to discover microlensing events, but also yielded high quality light curves to study variables. Using this data-set, the PS1 team presented ∼ 2000 Cepheids [29] and ∼ 300 eclipsing binaries [30]. The catalog of the Cepheids can be found at the VizieR Online Data Catalog, associated with the work of Kodric et al (2013, [29]).…”

M31, our closest neighboring galaxy, is a stepping stone to studies of stellar evolution, star formation, galaxy evolution, and cosmology. However, due to the difficulties of performing photometry in such crowded fields and the lack of wide cameras to encompass the entire galaxy, there has not been a complete census of the stellar contents of M31. The advent of wide-field camera provides us a unique opportunity to have a complete view of our neighboring galaxy, enabling an inventory of its variable content. We present a review of recent progresses of wide-field, high cadence surveys of M31, covering different population of variables and transients. We also outline future studies enabled by on-going and up-coming facilities.
