Synergies between Exoplanet Surveys and Variable Star Research [PDF]

open access: yesEPJ Web of Conferences, 2017
With the discovery of the first transiting extrasolar planetary system back to 1999, a great number of projects started to hunt for other similar systems.

Imbalance Learning for Variable Star Classification [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
The accurate automated classification of variable stars into their respective subtypes is difficult. Machine learning–based solutions often fall foul of the imbalanced learning problem, which causes poor generalization performance in practice ...

Scalable End-to-end Recurrent Neural Network for Variable star classification [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
During the last decade, considerable effort has been made to perform automatic classification of variable stars using machine-learning techniques. Traditionally, light curves are represented as a vector of descriptors or features used as input for many

A Catalog of RV Variable Star Candidates from LAMOST [PDF]

open access: yesAstrophysical Journal Supplement Series, 2020
Radial velocity (RV) variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ∼6.5 million stellar spectra in its Data Release 4 (DR4).

Sparse Identification of Variable Star Dynamics

open access: yesAstrophysical Journal, 2022
Variable stars play a crucial role as standard candles and provide valuable insights into stellar physics. They can be modeled either through fully fledged hydrodynamical simulations or analytically as systems of coupled differential equations describing

Variable Accretion onto Protoplanet Host Star PDS 70 [PDF]

open access: yesAstrophysical Journal, 2020
The PDS 70 system has been subject to many studies in the past year following the discovery of two accreting planets in the gap of its circumstellar disk. Nevertheless, the mass accretion rate onto the star is still not well known.

CCD VI time-series of the extremely metal-poor globular cluster M92: revisiting its variable star population [PDF]

open access: yes, 2020
We present an analysis of \emph{VI} CCD time-series photometry of the Oo II type globular cluster M92. The variable star population of the cluster is studied with the aim of revising their classifications, identifications, frequency spectra and to select
