Overview

• The triple-star system consists of HP Tau, HP Tau G2, and HP Tau G3.
• HP Tau is a T Tauri star, an early stage in stellar evolution before nuclear fusion begins.
• The stars are enveloped in a reflection nebula, which shines by reflecting nearby starlight.
• HP Tau's brightness varies due to chaotic processes and sunspots on its surface.
• Hubble's observations contribute to understanding protoplanetary disks and early star formation.
