The Random Transiter -- EPIC 249706694/HD 139139
S. Rappaport, A. Vanderburg, M. H. Kristiansen +16
We have identified a star, EPIC 249706694 (HD 139139), that was observed during K2 Campaign 15 with the Kepler extended mission that appears to exhibit 28 transit-like events over…
An ancient extrasolar system with five sub-Earth-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
Optical Spectroscopy of a Flare on Barnard's Star
D. Paulson, J. Allred, R. Anderson +3
We present optical spectra of a flare on Barnard's star. Several photospheric as well as chromospheric species were enhanced by the flare heating. An analysis of the Balmer lines s…
KOI-3158: The oldest known system of terrestrial-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. Whil…
The GAPS programme at TNG XLIX. TOI-5398, the youngest compact multi-planet system composed of an inner sub-Neptune and an outer warm Saturn
G. Mantovan, L. Malavolta, S. Desidera +68
Short-period giant planets are frequently found to be solitary compared to other classes of exoplanets. Small inner companions to giant planets with 15 days are known…
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…
