Kepler Eclipsing Binary Catalog

Catalog of 2,177 eclipsing binary systems identified by the Kepler mission, with orbital periods, morphology parameters, and stellar properties.

Dataset description

Eclipsing binaries are pairs of stars whose orbital plane is aligned with our line of sight, producing periodic dips in brightness as one star passes in front of the other. The Kepler mission's exquisite photometric precision made it ideal for detecting and characterizing these systems. This catalog from Slawson et al. (2011) provides the definitive Kepler eclipsing binary list with orbital periods, eclipse morphology parameters, and derived stellar properties.

Quick stats

2,177 eclipsing binaries
2,177 with measured orbital periods
2,022 with effective temperature estimates
Median orbital period: 1.851 days

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/kepler-eclipsing-binaries", split="train")
df = ds.to_pandas()

# Short-period binaries (< 1 day)
if "period_days" in df.columns:
    short = df[df["period_days"] < 1.0]
    print(f"{len(short):,} short-period binaries")

# Period distribution
import matplotlib.pyplot as plt
if "period_days" in df.columns:
    df["period_days"].dropna().hist(bins=100, log=True)
    plt.xlabel("Orbital Period (days)")
    plt.ylabel("Count")
    plt.title("Kepler EB Period Distribution")
