Domain-Informed Multi-View Self-Distillation for Astronomical Light-Curve Representation Learning with JEPA
Yicheng Rui
Light curves describe temporal variations in the brightness of celestial objects. Learning robust representations of light curves is essential for large-scale automatic discovery i…
AstroSkyFlow: an astronomical sky image flow simulator for time domain survey validation and machine learning
Kexin Li, Yicheng Rui, Fabo Feng +5
Modern time-domain optical surveys produce massive data volumes that require robust, high-fidelity simulated datasets for developing and validating automated pipelines and machine-…
LenghuSky-8: An 8-Year All-Sky Cloud Dataset with Star-Aware Masks and Alt-Az Calibration for Segmentation and Nowcasting
Yicheng Rui, Xiao-Wei Duan, Licai Deng +9
Ground-based time-domain observatories require minute-by-minute, site-scale awareness of cloud cover, yet existing all-sky datasets are short, daylight-biased, or lack astrometric…
A universal brown dwarf desert formed between planets and stars
Kaiming Cui, Guang-Yao Xiao, Fabo Feng +10
Giant planets and brown dwarfs play a crucial role in star and planet formation, as they are situated at the boundary between planets and stars with uncertain formation mechanisms.…
Detection of dark companions via the combination of eclipse timing variation, Hipparcos and/or Gaia astrometry: the cases of V Puppis and CY Ari
Guang-Yao Xiao, Fabo Feng, Song Wang +3
The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around…
Segmented-Polynomial-fitting Least Squares (SPLS): An optimized algorithm to find Earth twins
Shuyue Zheng, Fabo Feng, Yicheng Rui
Detecting Earth twins remains challenging because their shallow, long-period transits are difficult to distinguish from background noise. Motivated by the challenge, we developed S…
DeepAP: Deep Learning-based Aperture Photometry Feasibility Assessment and Aperture Size Prediction
Zheng-Jun Du, Qing-Quan Li, Yi-Cheng Rui +6
Aperture photometry is a fundamental technique widely used to obtain high-precision light curves in optical survey projects like Tianyu. However, its effectiveness is limited in cr…
Architecture of Tianyu Software: Relative Photometry as a Case Study
Yicheng Rui, Yifan Xuan, Shuyue Zheng +8
Tianyu telescope, an one-meter robotic optical survey instrument to be constructed in Lenghu, Qinghai, China, is designed for detecting transiting exoplanets, variable stars and tr…
A Cartesian catalog of 30 million Gaia sources based on second-order and Monte Carlo error propagation
Luyao Zhang, Fabo Feng, Yicheng Rui +2
Accurate measurements of stellar positions and velocities are crucial for studying galactic and stellar dynamics. We aim to create a Cartesian catalog from Gaia DR3 to serve as a h…
Tianyu: search for the second solar system and explore the dynamic universe
Fabo Feng, Yicheng Rui, Zhimao Du +32
Giant planets like Jupiter and Saturn, play important roles in the formation and habitability of Earth-like planets. The detection of solar system analogs that have multiple cold g…
Modeling and Calibration of Gaia, Hipparcos, and Tycho-2 astrometric data for the detection of dark companions
Fabo Feng, Yicheng Rui, Yifan Xuan +1
Hidden within the Gaia satellite's multiple data releases lies a valuable cache of dark companions. To facilitate the efficient and reliable detection of these companions via combi…
Mitigating astrometric bias in barycentric correction with PEXO
Yicheng Rui, Fabo Feng
Extremely precise radial velocity is essential for the detection of sub-m/s radial velocity of stars induced by Earth-like planets. Although modeling of the barycentric correction…
Revised orbits of the two nearest Jupiters
Fabo Feng, R. Paul Butler, Steven S. Vogt +2
With its near-to-mid-infrared high contrast imaging capabilities, JWST is ushering us into a golden age of directly imaging Jupiter-like planets. As the two closest cold Jupiters,…
Binary Star Evolution in Different Environments: Filamentary, Fractal, Halo and Tidal-tail Clusters
Xiaoying Pang, Yifan Wang, Shih-Yun Tang +7
Using membership of 85 open clusters from previous studies (Pang et al. 2021a,b, 2022b; Li et al. 2021) based on Gaia DR3 data, we identify binary candidates in the color-magnitude…
