HST FUV spectroscopy of the short orbital period recurrent nova CI Aql: Implications for white dwarf mass evolution

Edward M. Sion, R. E. Wilson, Patrick Godon +3

An HST COS Far UV spectrum (1170 A to 1800 A) was obtained for the short orbital period recurrent novae (T Pyxidis subclass), CI Aquilae. CI Aql is the only classical CV known to h…

A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters

T. Masseron, D. A. García-Hernández, Sz. Mészáros +12

We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…

SPHERE dynamical and spectroscopic characterization of HD142527B

R. Claudi, A. -L. Maire, D. Mesa +50

We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…

New Near-Infrared light-curve templates for RR Lyrae variables

V. F. Braga, P. B. Stetson, G. Bono +34

We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…

Stellar Proper Motions in the Orion Nebula Cluster

Dongwon Kim, Jessica R. Lu, Quinn Konopacky +5

The Orion Nebula Cluster (ONC) is the nearest site of ongoing massive star formation, which allows us to study the kinematics and dynamics of the region in detail and constrain sta…
