Part of a dataset collection on Hugging Face.
Dataset description
The fourth data release of the GALactic Archaeology with HERMES (GALAH) survey, providing radial velocities, stellar parameters, and up to 31 elemental abundances for 917,588 stars observed with the HERMES spectrograph on the Anglo-Australian Telescope.
GALAH DR4 is one of the largest stellar spectroscopic surveys… See the full description on the dataset page: https://huggingface.co/datasets/juliensimon/galah-dr4-stellar-abundances.sspp-dr9-stellar-spectra
SDSS SSPP DR9 Stellar Spectra Dataset
Dataset Summary
This dataset contains 233,013 stellar spectra from the
Sloan Digital Sky Survey (SDSS) Stellar Parameter Pipeline (SSPP) DR9,
cross-matched with SEGUE1/SEGUE2 spectroscopic observations.
Each sample contains a flux-calibrated 1D spectrum (3,878 wavelength bins,
~3,820–9,200 Å) plus stellar atmospheric parameters measured by the SSPP.

Overview
This directory hosts a stellarator configuration dataset grouped by number
of field periods (nfp). Each sample keeps only three things:
Fourier boundary coefficients, nfp, and 9 VMEC evaluation metrics —
every field is guaranteed to be non-None /… See the full description on the dataset page: https://huggingface.co/datasets/SII-AI4Fusion/SII-Stellarator-Configuration-Dataset.gaia-dr3-young-stellar-objects
Gaia DR3 Young Stellar Objects
Part of the Astronomy Datasets collection on Hugging Face.
The Gaia DR3 young stellar object (YSO) catalog, containing 79,375 YSO candidates
identified by the ESA Gaia mission's variability classification pipeline. Each source includes
a YSO classification confidence score, variability statistics (amplitudes, standard deviations,
skewness, kurtosis), astrometry (positions, parallax, proper motions), and multi-band
photometry (G, BP, RP).… See the full description on the dataset page: https://huggingface.co/datasets/juliensimon/gaia-dr3-young-stellar-objects.near-axis-stellarators
NearAxisStellarators
The NearAxisStellarators dataset contains stellarator configurations generated with the pyQSC near-axis expansion code.It provides input design parameters (magnetic axis Fourier coefficients, field strength coefficients, number of field periods, pressure) and the resulting plasma properties (rotational transform, elongation, Mercier stability, quasisymmetry, etc.).
This dataset supports both forward modeling (parameters → properties) and inverse design (desired… See the full description on the dataset page: https://huggingface.co/datasets/pedrocurvo/near-axis-stellarators.stellar-datasetsgeneva-copenhagen-stellar-survey
Geneva-Copenhagen Survey of Solar Neighbourhood
Part of the Astronomy Datasets collection on Hugging Face.
The Geneva-Copenhagen Survey (GCS) is a comprehensive catalog of 16,682 F and G dwarf
stars in the solar neighbourhood, providing ages, metallicities, and full 3D space velocities.
It is one of the most widely used datasets for studying the chemical and dynamical evolution
of the Milky Way disk.
Dataset description
The GCS combines Stromgren photometry, Hipparcos… See the full description on the dataset page: https://huggingface.co/datasets/juliensimon/geneva-copenhagen-stellar-survey.stellar_classificationstellar_classification_missing
