+# 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
+
+```python
+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")
+```
