The Deuterium Isotopic Ratio of Water Released From the Martian Caps as Measured With TGO/NOMAD

نویسندگان

چکیده

We report vertical profiles of water and D/H for one Martian year as measured with the TGO/NOMAD instrument. The observations were performed via solar occultation, providing up to ?100 km ?60 km, a resolution 1–2 km. measurements reveal dramatic variability over short timescales altitude location on planet. investigated release seasonal from polar caps during southern northern summer, by mapping its near regions. Above hygropause, drops substantially below 2 VSMOW, both show consistent enriched 5–7 VSMOW within hygrosphere.

determinant of the hankel matrix with binomial entries

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
