Abstract
We present the first scientific results of the program on short term period variable stars observed at OAUNI at the peruvian Andes. These results include good quality light curves of delta Scuti stars, rapidly oscillating stars along with eclipsing and cataclysmic binaries. The photometric precision reached by the available instrumental and equipment, and used in the several scientific subprograms, has satisfied the initial expectations.
Highlights
The astronomical observatory of The NationalUniversity of Engineering (OAUNI [1,2]) operates at the peruvian central Andes (Huancayo, 3300 m.u.s.l.) since2015
This ongoing effort aims to provide of a facility to develop science programs, teaching and outreach in astronomy
In this work we present the preliminary reduction of one star as example in each subprogram of the OAUNI
Summary
University of Engineering (OAUNI [1,2]) operates at the peruvian central Andes (Huancayo, 3300 m.u.s.l.) since. Between its prioritized scientific programs is the monitoring of short term period variables stars This program was chosen to test the OAUNI capabilities to gather complete light curves for objects with periods less than one night (up to eight hours) and to test stellar microvariability (periods in order of minutes) in selected astrophysical objects. The OAUNI program of short term period variable stars includes several types of systems. The pulsations are a consequence of the supplied energy in the internal ionizations zones of elements as helium Both radial and non-radial oscillations occur in delta Scuti stars. Those are generally low order pressure modes with periods between tens of minutes and several hours. The observed amplitudes span from thousandths up to tenths of a magnitude [6]
