LIGHT CURVE REDUCED OF COMET 46/WIRTANEN SCIENTIFIC RESULTS

Imagen
Based on my analysis of the reduced light curve of comet 46p, based on 990 measurements, being the world's largest light curve, the preliminary scientific results are: Estimated diameter 0.96 kms, Estimated active surface area ~ 50km2, Water production rate Q (H2O) ~ 10 ^ 29.5 mol sec = 5 tons per second of water, it is observed that ar = 1.25 au, there is a change in the predominant chemical volatility being Q H2O> Q CO +, these results are preliminary, until completing the light curve, and are based on the following scientific references: Sosa, Fdez (2011), Yang (2008), Navarro (2018), MPC / IAU, Cobs.si, Observerscometas yahoogroups.com (Navarro owner).

PRELIMINARY ANALYSIS OF THE CURVE OF VISUAL LIGHT AND CCD OF THE COMET 46 P / WIRTANEN

Imagen
ABSTRACT A preliminary analysis of the visual light curve and ccd of Comet 46P / Wirtanen with 990 visual measurements and ccd obtained from the sources MPC / IAU, COBS database, and observadorescometas yahoogroups.com (Navarro Pina Administrator) is made, being the largest curve of light until the moment of this comet, are determined, the photometric parameters of the comet, absolute magnitude (m0), and rate of increase in brightness or activity index (n), as well as an analysis and revision of the physical parameters, diameter of the nucleus, mass, rate of water production, also the author, studies the correlation between magnitudes ccd (mccd) and visual (m1), finding an increase in time with a difference of 100 days of 4.4 magnitudes, and obtaining the equations [ d (m1-mccd) T-20 = 6.1 mag. ] and [ d (m1-mccd) T-20 = 1.7 mag.] 1. INTRODUCTION AND RESUME Studying the resulting light curve at only 20 days for perihelion, we found, with 990 visual observations and ccd collected f…
