ABSTRAKDi permukaan bintang neutron, perubahan kerapatan partikel yang signi kan dapat
menghasilkan separasi muatan dalam bentuk lapisan dipol listrik. Pada penelitian
ini dipelajari efek medan listrik akibat lapisan tersebut terhadap properti dari bintang
neutron. Untuk memodelkan kerapatan lapisan dipol listrik, kami menggunakan
dua fungsi Gaussian. Pada perhitungan ini kami gunakan dua model dengan
asumsi berbeda, yakni: model dengan asumsi bahwa bintang neutron hanya tersusun
atas p, n, e dan serta model dengan asumsi bintang neutron tersusun dari p, n, e,
dan hyperon. Hasil yang diperoleh menunjukkan bahwa massa maksimum tidak
sensitif terhadap medan listrik di permukaan, tetapi radius bintang dengan massa
kanonik 1:4Mb cukup sensitif terhadap medan listrik. Bintang neutron dengan
hyperon bersifat lebih soft dibandingkan bintang neutron tanpa hyperon
ABSTRACTOn the surface of a neutron star, a signi cant particle density changes can produce
charge separation in the form electric dipole layer. This research studied electric
eld e ect from the dipole layer on the properties of neutron star. For modeling
electric dipole layer density, we use two Gaussian functions. We use two models
with di erent assumptions: namely a model which assumes the neutron star is only
composed of p, n, e and and a model which assumes the neutron star is composed of
p, n, e, and hyperon. The result showes that the maximum mass is not sensitive to
the electric elds on the surface, but the radius of star with canonical mass 1:4Mb
is quite sensitive to electric elds. The neutron star with hyperon is softer than
without hyperon;On the surface of a neutron star, a signi cant particle density changes can produce
