Collaborative Research: Explaining the Orbits of Eccentric Warm Jupiters — NSF Award to Indiana University (IN, $300,202)
The orbits of planetary systems hold clues about their origins. Gas giants like Jupiter are thought to form on circular orbits far from stars. However, exoplanets with large eccentricity abound, and the “hot Jupiter” class have orbital periods of just a few days. In some cases, extremely eccentric planets may approach

| Abstract | The orbits of planetary systems hold clues about their origins. Gas giants like Jupiter are thought to form on circular orbits far from stars. However, exoplanets with large eccentricity abound, and the “hot Jupiter” class have orbital periods of just a few days. In some cases, extremely eccentric planets may approach their stars, where tidal forces deform them, dissipate energy, and ultimately circularize their orbits—a hypothesis known as high-eccentricity migration (HEM), which is the likely |
