Photometric Observations of LO Peg in 2017

New observations of the ultrafast rotator of the K3 spectral type, the star LO Peg, were carried out using a robotic wide-angle observation system in the Zvenigorod observatory of INASAN in 2017. Temperature-inhomogeneity maps on the LO Peg surface were reconstructed using the light curves, and the longitudes corresponding to the position of active regions were determined. The ongoing evolution of moving active regions and the phenomenon of switching positions of active longitudes in 2017 were established. The area of the star covered with spots has stopped decreasing and by now reach 17% of the area of its total visible surface. We defined more accurately the cycles of the long-period variability of LO Peg and noticed considerable changes in the shape of the power spectrum. Among cycles of the longterm variability greater than five years, only two cycles of 5.55 and 9.25 yrs began to appear. Based on analyzing the diagrams illustrating the relationship of the spot parameter with rotation, age, and Rossby numbers for LO Peg, 1570 M-dwarf stars, and eight objects from the Pleiades cluster with masses corresponding to the mass estimate for LO Peg (0.75 M_⊙), the conclusion was drawn about the increased activity (spottedness) of LO Peg in comparison with similar objects.  相似文献   

Perspectives for Distributed Observations of Near-Earth Space Using a Russian–Cuban Observatory

The creation of a specialized network of large, wide-angle telescopes for distributed observations of near-Earth space using a Russian–Cuban Observatory is considered. An extremely important goal of routine monitoring of near-Earth and near-Sun space is warding off threats with both natural and technogenic origins. Natural threats are associated with asteroids or comets, and technogenic threats with man-made debris in near-Earth space. A modern network of ground-based optical instruments designed to ward off such threats must: (a) have a global and, if possible, uniform geographic distribution, (b) be suitable for wide-angle, high-accuracy precision survey observations, and (c) be created and operated within a single network-oriented framework. Experience at the Institute of Astronomy on the development of one-meter-class wide-angle telescopes and elements of a super-wide-angle telescope cluster is applied to determine preferences for the composition of each node of such a network. The efficiency of distributed observations in attaining maximally accurate predictions of the motions of potentially dangerous celestial bodies as they approach the Earth and in observations of space debris and man-made satellites is estimated. The first estimates of astroclimatic conditions at the proposed site of the future Russian–Cuban Observatory in the mountains of the Sierra del Rosario Biosphere Reserve are obtained. Special attention is given to the possible use of the network to carry out a wide range of astrophysical studies, including optical support for the localization of gravitational waves and other transient events.  相似文献
