We present a study of the X-ray coronal emission from the active binary VY\nAri, using data from both the Low Energy Concentrator Spectrometer (LECS) and\nthe Medium Energy Concentrator Spectrometer (MECS) instruments on-board the\nX-ray satellite BeppoSAX. Using these instruments, the X-ray spectrum of VY Ari\ncan be studied across two full decades of energy, from 0.1 to 10 keV. The\nspectrum is well fit, across the whole spectral range, with an optically thin\nplasma MEKAL model with two discrete temperature components, and with an\ninferred coronal abundance feh \≃ -0.4, corresponding to the average\ntypical value of the photospheric abundance in RS CVn-type binaries.\n
