Brown dwarfs older than ∼10 Myr are expected to possess short-lived magnetic fields and to emit weak radio and X-rays emission. So far, radio emission is detected from only a handful of brown-dwarfs (such as LP944-20). Here we present a study to systematically look for radio emission from various brown-dwarf systems using various existing surveys. We also present a study of overall radio emission from the all known brown-dwarfs location using stacking. |
