Solaris photometric survey: Search for circumbinary companions using eclipse timing variations
Ayush Moharana, K. G. Hełminiak, F. Marcadon +8
Eclipse timing variations (ETV) have been a successful tool for detecting circumbinary companions to eclipsing binaries (EB). While TESS and Kepler have been prolific for ETV searc…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue -- XII. A sample of systems with photometry
K. G. Hełminiak, A. Moharana, T. Pawar +10
We present results of the analysis of light and radial velocity (RV) curves of eight detached eclipsing binaries observed by the All-Sky Automated Survey, which we have followed up…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue -- XI. CHIRON investigation of long-period binaries
M. Ratajczak, R. K. Pawłaszek, K. G. Hełminiak +8
We present the results of a spectroscopic campaign on eclipsing binaries with long orbital period (P = 20 - 75 d) carried out with the CHIRON spectrograph. Physical and orbital sol…
Analysis of eclipsing binaries in multiple stellar systems: the case of V1200 Centauri
F. Marcadon, K. G. Hełminiak, J. P. Marques +5
We present a new analysis of the multiple star V1200 Centauri based on the most recent observations for this system. We used the photometric observations from the Solaris network a…
Orbital and physical parameters of eclipsing binaries from the All-Sky Automated Survey catalogue - X. Three high-contrast systems with secondaries detected with IR spectroscopy
K. G. Hełminiak, A. Tokovinin, E. Niemczura +13
We present results of the combined photometric and spectroscopic analysis of three detached eclipsing binaries, which secondary components are not visible or very hard to identify…
Tracking the spin axes orbital alignment in selected binary systems - Torun Rossiter-McLaughlin effect survey
P. Sybilski, R. K. Pawłaszek, A. Sybilska +4
We have obtained high-resolution spectra of four eclipsing binary systems (FM Leo, NN Del, V963 Cen and AI Phe) with the view to gaining insight into the relative orientation of th…
HIDES spectroscopy of bright detached eclipsing binaries from the field - I. Single-lined objects
K. G. Hełminiak, N. Ukita, E. Kambe +5
We present results of our spectroscopic observations of nine detached eclipsing binaries (DEBs), selected from the Eclipsing Binary Catalog, that only show one set of spec…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue - VIII. The totally-eclipsing double-giant system HD 187669
K. G. Hełminiak, D. Graczyk, M. Konacki +14
We present the first full orbital and physical analysis of HD 187669, recognized by the All-Sky Automated Survey (ASAS) as the eclipsing binary ASAS J195222-3233.7. We combined mul…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue - IV. A 0.61 + 0.45 M_sun binary in a multiple system
K. G. Hełminiak, M. Konacki, M. Rozyczka +12
We present the orbital and physical parameters of a newly discovered low-mass detached eclipsing binary from the All-Sky Automated Survey (ASAS) database: ASAS J011328-3821.1 A - a…
