The two objects 1SWASP J150822.80−054236.9 and 1SWASP J160156.04+202821.6 were initially detected from their SuperWASP archived light curves as candidate eclipsing binaries with periods close to the short-period cut-off of the orbital period distribution of main sequence binaries, at∼0.2 d. Here, using INT spectroscopic data, we confirm them as d ouble-lined spectroscopic and eclipsing binaries, in contact configuration. Following modelling of their visual light curves and radial velocity… 
We present a photometric study of the short-period eclipsing binary NSVS4484038. Time-series CCD photometry of the star in the B and V band was carried out. An orbital period of 0.218551 days was
Ultrashort-period main-sequence eclipsing systems: new observations and light-curve solutions of six NSVS binaries
We carried out photometric and low-resolution spectral observations of six eclipsing ultrashort-period binaries with MS components. The light curve solutions of the Rozhen observations show that all
1SWASP J034439.97+030425.5: a short-period eclipsing binary system with a close-in stellar companion
First multi-wavelength photometric light curves (LCs) of the short-period eclipsing binary (EB) 1SWASP J034439.97+030425.5 (hereafter J0344) are presented and analyzed by using the 2013 version of
The first sets of high-quality light curves of the extremely short period eclipsing binary 1SWASP J074658.62+224448.5 (hereafter J074658) were obtained in 2012 and 2014. The photometric solutions
Light curve solutions of six eclipsing binaries at the lower limit of periods for W UMa stars
Photometric observations are presented in V and I bands of six eclipsing binaries at the lower limit of the orbital periods for W UMa stars. Three of them are newly discovered eclipsing systems. The
Orbital period cut-off of W UMa-type contact binaries
Period cut-off and period–colour relation are two special characters of W UMa-type contact binaries. In the past, many authors noted these two properties, however, a comprehensive study was still
SuperWASP discovery and SALT confirmation of a semi-detached eclipsing binary that contains a δ Scuti star
We searched the SuperWASP archive for objects displaying multiply periodic photometric variations. Specifically we sought evidence for eclipsing binary stars displaying a further non-harmonically
The First Light Curve Modeling and Orbital Period Change Investigation of Nine Contact Binaries around the Short-period Cutoff
In this paper, we present the first light curve synthesis and orbital period change analysis of nine contact binaries around the short-period limit. It is found that all these systems are W-subtype
1SWASP J075102.16+342405.3: A deep overcontact binary system with a period under the short period cut-off
New photometry of two different seasons for the extremely short period eclipsing binary 1SWASP J075102.16+342405.3 were performed. The two sets of derived light curves show a large difference in
Light curve analysis of six totally eclipsing W UMa binaries
We analyze multicolor light curves of six totally eclipsing, short-period W UMa binaries and derive, for the first time, their orbital and stellar parameters. The mass ratios are established


The short-period end of the contact binary period distribution based on the All-Sky Automated Survey
The search volume-corrected period distribution of contact binaries of the W UMa type appears to reflect primarily the constant number ratio of ≃1/500 to the number of stars along the main sequence;
The short-period limit of contact binaries
The stability of mass transfer is important in the formation of contact binaries from detached binaries when the primaries of the initially detached binaries fill their Roche lobes. Using Eggletons
Period and period change measurements for 143 SuperWASP eclipsing binary candidates near the short-period limit and discovery of a doubly eclipsing quadruple system
Building on previous work, a new search of the SuperWASP archive was carried out to identify eclipsing binary systems near the short-period limit. 143 candidate objects were detected with orbital

Fundamental properties of lower main-sequence stars
The field of exoplanet research has revitalized interest in M dwarfs, which have become favorite targets of Doppler and transit surveys. Accurate measurements of their basic properties such as
Accurate masses and radii of normal stars: modern results and applications
This article presents and discusses a critical compilation of accurate, fundamental determinations of stellar masses and radii. We have identified 95 detached binary systems containing 190 stars (94

PHOEBE (PHysics Of Eclipsing BinariEs) is a modeling package for eclipsing binary stars, built on top of the widely used WD program of Wilson & Devinney. This introductory paper gives an overview of
Can full convection explain the observed short-period limit of the W UMa-type binaries?
Stars become fully convective at low effective temperatures. The unique mass-radius relation for fully convective stars (at a given effective temperature) cannot be reconciled with such a relation
