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")
