Asteroseismology of the fast-rotating high-amplitude $\delta$ Scuti star V2367 Cygni

Autor: Daszynska-Daszkiewicz, Jadwiga, Szewczuk, Wojciech, Walczak, Przemysław

We present the comprehensive analysis of the high-amplitude $\delta$ Sct star V2367 Cygni. Firstly, we perform the frequency analysis for the whole available set of the {\it Kepler} and {\it TESS} photometry. Most of the frequency peaks are harmonics

Asteroseismology of double-mode radial $\delta$ Scuti stars: AE Ursae Majoris and RV Arietis

Autor: Daszynska-Daszkiewicz, J., Walczak, P., Szewczuk, W., Niewiadomski, W.

Publikováno v: Monthly Notices of the Royal Astronomical Society, 2023

We construct complex seismic models of two high-amplitude delta Sct stars, AE UMa and RV Ari, each pulsating in two radial modes: fundamental and first overtone. The models reproduce, besides the frequencies of two radial modes, also the amplitude of

Are the functions of non-suicidal self-injury associated with its persistence and suicide risk in university students? Insights from a network analysis

Publikováno v: Frontiers in Psychiatry, Vol 15 (2024)

BackgroundTo date, a number of intra- and interpersonal functions of non-suicidal self-injury (NSSI) have been identified. Yet, their association with persistence of NSSI and suicide risk remains unknown. The study aimed to investigate which function

A need to revise stellar opacities from asteroseismology of $\delta$ Scuti stars

Autor: Daszyńska-Daszkiewicz, Jadwiga, Walczak, Przemysław, Pamyatnykh, Alexey, Szewczuk, Wojciech, Niewiadomski, Wojciech

We construct seismic models of the four double-mode radial $\delta$ Scuti stars adopting opacities from three databases: OPAL, OP and OPLIB. The aim is to find the models that fit the observed frequencies of the two radial modes and have the effectiv
