Milky Way Globular Star Clusters

Part of the Astronomy Datasets collection on Hugging Face.

A comprehensive catalog of 170 Milky Way globular clusters, merging two authoritative sources: the Harris (2010 edition) catalog for metallicities and photometry, and the Baumgardt globular cluster database for dynamical masses, velocity dispersions, and structural parameters from N-body model fits to Gaia DR3 proper motions and HST data.

Dataset description

Globular clusters are ancient, gravitationally bound collections of stars orbiting the Milky Way. They are among the oldest objects in the Galaxy (10--13 Gyr), with typical masses of 10⁴--10⁶ M☉ and half-light radii of a few parsecs. Their metallicities, dynamics, and spatial distribution encode the formation and assembly history of the Milky Way.

This dataset combines Harris (2010) photometric and chemical data with Baumgardt's dynamical parameters derived from N-body fits to modern astrometric and spectroscopic data, providing the most complete per-cluster view available.

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/globular-star-clusters", split="train")
df = ds.to_pandas()

# Most massive clusters
massive = df.nlargest(10, "mass_msun")[["name", "mass_msun", "metallicity_fe_h"]]

# Metal-poor vs metal-rich populations
metal_poor = df[df["metallicity_fe_h"] < -1.5]
metal_rich = df[df["metallicity_fe_h"] >= -1.5]

# Core-collapsed clusters
cc = df[df["core_collapsed"]]

# Mass-metallicity relation
import matplotlib.pyplot as plt
plt.scatter(df["metallicity_fe_h"], df["mass_msun"].apply(lambda x: x if x else None))
plt.xlabel("[Fe/H]"); plt.ylabel("Mass (M☉)"); plt.yscale("log")
