Abstract Galactic short-period close white dwarf binaries (CWDBs) are important objects for space-borne gravitational-wave (GW) detectors in the millihertz frequency bands. Due to intrinsically low luminosity, only about 25 identified CWDBs detectable by Laser Interferometer Space Antenna (LISA), which also known as verification (VBs). The Gaia Early Data Release 3 (EDR3) provids a catalog containing large number of CWDB candidates, includes parallax and photometry measurements. We...
Context. A new X-ray Cataclysmic variable (CV) candidate exhibits distinct light-curve characteristics in the ZTF’s g , r and i bands. The paper includes optical identification multiwavelength analysis of this CV candidate. Aims. This work aims to determine if a previously identified candidate, ZTF J0112+5827, is polar system by examining its cyclotron radiation characteristics. Methods. We characterized emission J0112+5827 using ROSAT observations. gri -band light curves were obtained from...
Abstract Extremely low-mass (ELM) white dwarfs (WDs) are helium-core WDs with masses less than 0.3 M ⊙ . Short-period ELM WD binaries that exhibit ellipsoidal variations may harbor heavier companions, either massive or millisecond pulsars (MSPs). In this study, we selected ∼12,000 their candidates, and searched for ellipsoidal-like lightcurves orbital periods shorter 1 day, by using the public data from Zwicky Transient Facility. Finally, 23 such systems were found, 17 being newly...
Close white dwarf binaries (CWDBs) are considered to be progenitors of several exotic astronomical phenomena (e.g., type Ia supernovae, cataclysmic variables). These violent events broadly used in studies general relativity and cosmology. However, obtaining precise stellar parameter measurements for both components CWDBs is a challenging task given their low luminosities, swift time variation, complex orbits. High-resolution spectra (R$> 20 000$) preferred but expensive, resulting sample...
Spider pulsars constitute a distinct subset within the domain of radio millisecond pulsars, divided further into categories black widows and redbacks. Evident across multiple wavelengths, these manifest periodic variations reside binary systems. Investigating discovering additional spider-type carries significant implications for comprehending evolution high-mass stars. Particularly crucial is validation "Recycling" theory pulsar genesis. In this investigation, we systematically explore...
Abstract Spider pulsars represent a unique subclass of radio millisecond in binaries, and are further categorized into black widows redbacks according to the mass low-mass companion. These pulsars, observable across multiple wavelengths, exhibit periodic variability optical. The discovery study additional spider-type crucial for fuller understanding evolution binary stars close orbits recycling theory pulsars. In this work, we systematically searched spider pulsar systems using time-domain...
