The Eclipsing Scuti Star EPIC 245932119
Jae Woo Lee, Kyeongsoo Hong, Martti H. Kristiansen
We present the physical properties of EPIC 245932119 ( = 9.82) exhibiting both eclipses and pulsations from the {\it K{\rm 2}} photometry. The binary modeling indicat…
Mass function and dynamical study of the open clusters Berkeley 24 and Czernik 27
D. Bisht, R. K. S. Yadav, Shashikiran Ganesh +3
We present a photometric study of the open clusters Berkeley 24 (Be 24) and Czernik 27 (Cz 27). The radii of the clusters are determined as 2\farcm7 and 2\farcm3 for Be 24 a…
Photodynamical analysis of the triply eclipsing hierarchical triple system EPIC 249432662
T. Borkovits, S. Rappaport, T. Kaye +16
Using Campaign 15 data from the K2 mission, we have discovered a triply-eclipsing triple star system: EPIC 249432662. The inner eclipsing binary system has a period of 8.23 days, w…
Characterization of Low Mass K2 Planet Hosts Using Near-Infrared Spectroscopy
Romy Rodríguez Martínez, Sarah Ballard, Andrew Mayo +3
We present moderate resolution near-infrared spectra in and band of M dwarf hosts to candidate transiting exoplanets discovered by NASA's K2 mission. We employ known emp…
SN 2017ens: The Metamorphosis of a Luminous Broad-lined Type Ic Supernova into an SN IIn
T. -W. Chen, C. Inserra, M. Fraser +46
We present observations of supernova (SN) 2017ens, discovered by the ATLAS survey and identified as a hot blue object through the GREAT program. The redshift z=0.1086 implies a pea…
3-Phase Evolution of a Coronal Hole, Part I: 360° remote sensing and in-situ observations
S. G. Heinemann, M. Temmer, S. J. Hofmeister +2
We investigate the evolution of a well-observed, long-lived, low-latitude coronal hole (CH) over 10 solar rotations in the year 2012. By combining EUV imagery from STEREO-A/B and S…
