Evidence for Dynamical Filtering: High Binary Fraction, Hard-binary Excess, and Unresolved Triples in the Surviving Core of NGC 6791

Huanbin Chi, Zhi Li, Feng Wang +4

We present a deep photometric analysis of the main-sequence (MS) population in the old, metal-rich open cluster (OC) NGC 6791 using Gaia Data Release 3 data. After correcting for d…

Research Progress on Solar Small-Scale Dynamo

Wen-Jie Jiang, Lei Ni, Chun-Lan Jin +2

The small-scale solar dynamo theory, as the core mechanism explaining the origin of the persistent, disperse weak magnetic field in the quiet Sun regions, has made significant prog…

A very rapidly rotating white dwarf in nova YZ Reticuli

G. J. M. Luna, N. Rawat, R. Angeloni +4

YZ Ret (Nova Reticuli 2020) is the first VY Scl-type nova-like variable observed to undergo a classical nova eruption. Following the outburst, timing analysis of 20-s cadence TESS…

The Be star omicron Cas is indeed the primary of a triple system

Petr Harmanec, Stephenson Yang, Miroslav Slechta +3

Analysis of radial velocities of two narrow absorption components in the Mg II 4481 A line demonstrated that the secondary of the Be star omicron Cas is indeed a close binary syste…

Rapidly oscillating Ap stars observed with TESS. The LAMOST Ap sample and 49 Cam

Inês Rolo, Daniel L. Holdsworth, Margarida S. Cunha +4

The rapidly oscillating chemically peculiar A-type (roAp) stars offer valuable insights into the internal physical processes of all stars, but their study is challenged by their ra…

Discovery of the First Octupole Pulsation Mode in a delta Scuti Star: A Stationary l = 3 Sectoral Mode

S. A. Rappaport, R. Jayaraman, G. Handler +8

Aims. We are attempting to better understand how stellar pulsations in close binary systems are affected, and possibly induced, by tidal, Coriolis, and centrifugal forces. Methods.…
