ABSTRACT Recently, high-precision optical 2-min cadence light curves obtained with TESS
for targets located in the mission's defined first four sectors have been released. The majority …

We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars
using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS) …

The driving mechanism for high-frequency oscillations in some chemically peculiar Ap stars,
the rapidly oscillating Ap stars (roAp stars), is not understood. The Transiting Exoplanet …

Since the discovery of the spectral peculiarities of their prototype α2 Canum Venaticorum in
1897, the so-called ACV variables, which are comprised of several groups of chemically …

Delta-a system photometry of the sample of Ap stars from Bidelman and McConnell's (1973)
catalogue is discussed. Comparing delta-a measurements in four marginally different …

We present the first comprehensive catalog of the γ Doradus type pulsating stars. This
catalog covers observational properties of all γ Dor variables obtained until January 2017 …

We present our extensive project of the On‐line database of photometric observations of
magnetic chemically peculiar stars to collect published data of photometric observations of …

We present multi-site photometric observations of the F0 IV star HR 2740≡ QW Pup that
reveal it to be a γ Dor type variable pulsating with four frequencies: 1.0434, 0.9951, 1.1088 …

Based on observations with the 6-m SAO RAS telescope, we have found that chemically
peculiar star with a large depression of the continuum at λ5200 Å and strengthened silicon …

An IR investigation has been conducted of eight southern, magnetically chemically peculiar
(CP2) stars brighter than sixth visual magnitudes. The data obtained show that CP2 stars …
