Halo oxygen-rich AGB stars catalog
Listed in IVOA Registry (Virtual Observatory)
To construct a catalogue of oxygen-rich (M) asymptotic giant branch (AGB) stars in the halo, complementing the catalogues of carbon-rich (C) stars, previous lists of Miras and SRa semi-regulars located in the northern hemisphere are merged and cleaned of various defects.
Description
After putting aside known C stars, characteristics such as colours and periods indicate that most of the remaining objects are M stars. Distances are obtained through the period-luminosity relation.
By considering their position in the sky, stars lying at |Z|>5kpc are confirmed to be in majority in the Sgr tidal arms. The M stars are more numerous than C ones. Our distance scale is supported by two cool variables located in the Pal 4 globular cluster.

Along the Sgr arms, there is reasonable agreement on distances of our objects with recent RR Lyrae distances. A few stars may be as distant as 150kpc, with possibly four at the trailing arm apocentre, and two in the A16 sub-structure, angularly close to two C stars. Ninety radial velocities are collected from Gaia and other sources.
A catalogue with 417 M pulsating AGB stars is provided. This catalogue contains about 260 stars in the halo with |Z|>5kpc. Their Ks magnitudes range from 8 up to 13.
For comparison, the catalogue also provides about 150 stars in the disc having 5<Ks<8.
