Despite this importance, it is very poorly known, with previous results varying by up to two orders of magnitude for a given speed. We present the most recent study of luminous efficiency values determined with modern high-resolution instruments, by directly comparing dynamic and photometric meteoroid masses. Fifteen non-fragmenting meteoroids were used, with a further five clearly fragmenting events for comparison. Twelve of the fifteen non-fragmenting meteoroids had luminous efficiencies less than 1%, while the fragmenting meteoroids had upper limits of a few tens of percent. No clear trend with speed was seen, but there was a weak negative trend of luminous efficiency on meteoroid mass, implying that smaller meteoroids radiate more efficiently. &#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dilini Subasinghe, Margaret Campbell-Brown Accepted December 19, 2017 to The Astronomical Journal PDF (OPEN ACCESS) &#8220;Luminous efficiency is a necessary parameter for determining meteoroid mass from optical emission.
