Indian researchers spot one of the shortest-period stellar binary system

• World's first confirmed discovery of a blue straggler star hosting a brown dwarf companion in an extraordinarily compact binary system, by an Indian-Italian team.
• Orbital period of just ~5.6 hours (0.234 days) — one of the shortest known stellar binary periods.
• Significant for UPSC under S&T (GS-III) — Indian astronomy leadership, DST-INSPIRE programme outcomes, and basic-science capability.
