Classification of Variable Star Light Curves with Convolutional Neural Network

Galaxies
The classification of variable stars is essential for understanding stellar evolution and dynamics. With the growing volume of light curve data from extensive surveys, there is a need for automated and accurate classification methods. Traditional methods

Synchronizability of multilayer star-ring networks with variable coupling strength

Electronic Research Archive, 2023
We investigate the synchronizability of multilayer star-ring networks. Two types of multilayer networks, including aggregated coupling and divergent coupling, are established based on the connections between the hub node and the leaf nodes in the ...

Discovery of a strong magnetic field in the rapidly rotating B2Vn star HR 7355 [PDF]

, 2010
We report the detection of a strong, organized magnetic field in the helium-variable early B-type star HR 7355 using spectropolarimetric data obtained with ESPaDOnS on the 3.6-m Canada-France-Hawaii Telescope within the context of the Magnetism in ...

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

Population Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

The identification of the optical companion to the binary millisecond pulsar J0610-2100 in the Galactic field

, 2012
We have used deep V and R images acquired at the ESO Very Large Telescope to identify the optical companion to the binary pulsar PSR J0610-2100, one of the black-widow millisecond pulsars recently detected by the Fermi Gamma-ray Telescope in the Galactic

V2494 cyg: A unique FU ori type object in the cygnus OB7 complex [PDF]

, 2013
A photometric and spectral study of the variable star V2494 Cyg in the L 1003 dark cloud is presented. The brightness of the star, formerly known as HH 381 IRS, increased by 2.5 mag in R (probably in the 1980s) and since then has remained nearly constant.

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

THE CHROMOSPHERE-LIKE ENVELOPE OF THE VARIABLE STAR T TAU

Odessa Astronomical Publications, 2017
The emission measure of the near-star chromosphere-like envelope of variable star T Tau with various mechanisms of radiation is computed. The normalization on the observed distribution of energy in continuum spectrum is carried out.
