We present observations and analysis of PSN J17292918+7542390 , a low-luminosity Type II-P supernova ( LL SN IIP ) .
The observed sample of such events is still low , and their nature is still under debate .
Such supernovae are similar to SN 2005cs , a well-observed low-luminosity Type II-P event , having low expansion velocities , and small ejected ^ { 56 } Ni mass .
We have developed a robust and relatively fast Monte-Carlo code that fits semi-analytic models to light curves of core collapse supernovae .
This allows the estimation of the most important physical parameters , like the radius of the progenitor star , the mass of the ejected envelope , the mass of the radioactive nickel synthesized during the explosion , among others .
PSN J17292918+7542390 has R _ { 0 } = 91 _ { -70 } ^ { +119 } \cdot 10 ^ { 11 } \text { cm } , M _ { \text { ej } } = 9.89 _ { -1.00 } ^ { +2.10 } M _ { \odot } , E _ { \mbox { kin } } = 0.65 _ { -0.18 } ^ { +0.19 } \text { foe } , v _ { \mbox { exp } } = 3332 _ { -347 } ^ { +216 } km s ^ { -1 } , for its progenitor radius , ejecta mass , kinetic energy and expansion velocity , respectively .
The initial nickel mass of the PSN J17292918+7542390 turned out to be 1.55 _ { -0.70 } ^ { +0.75 } \cdot 10 ^ { -3 } M _ { \odot } .
The measured photospheric velocity at the earliest observed phase is 7000 km s ^ { -1 } .
As far as we can tell based on the small population of observed low-luminosity Type II-P supernovae , the determined values are typical for these events .
