K-band spectroscopy of the intermediate polar XY Ari.


Abstract (from CDS):

We present the K-band infrared spectrum of the intermediate polar XY Ari. The spectrum confirms the cataclysmic binary nature of XY Ari, showing emission lines of Hei (λ2.0587µm) and the Brackett and Paschen series of Hi. The broad nature of these lines suggests an origin in an accretion disc. The spectrum is strongly reddened by absorption within the molecular cloud Lynds 1457 and shows prominent absorption features from the secondary star, from which we determine a spectral type for the secondary of M0V. The secondary contributes {formmu1} per cent of the K-band light. We derive a visual extinction to XY Ari of {formmu2} and a distance of {formmu3}, placing XY Ari behind the molecular cloud.
