Influence of the growth temperature and annealing on the optical properties of {CdO/ZnO}30 superlattices
E. Przeździecka, A. Lysak, A. Adhikari +6
Optical properties of the short period {CdO/ZnO} superlattices grown by plasma assisted MBE were analyzed. The superlattice (SLs) structures were successfully obtained at different…
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…
A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations
F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201
This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…
MBE grown preferentially oriented CdMgO alloy on m- and c-plane sapphire substrates
A. Adhikari, A. Lysak, A. Wierzbicka +4
Unlike other II-VI semiconductors, CdO-based transparent oxide has great potential application for the fabrication of many optoelectronic devices. In this work, we study the growth…
Effective Mg Incorporation in CdMgO Alloy on Quartz Substrate Grown by Plasma-assisted MBE
A. Adhikari, A. Wierzbicka, A. Lysak +3
The development of CdMgO ternary alloy with a single cubic phase is challenging but meaningful work for technological advancement. In this work, we have grown a series of Cd1-xMgxO…

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…
