Beichman et al. 2016 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)1BEICHMAN ET AL 2016 . We have used theSpitzer Space Telescope to observe two transiting planetary systemsorbiting low mass stars discovered in theKepler K2mission. The system K2-3 (EPIC201367065) hosts three planets while EPIC 202083828 (K2-26) hosts a single planet. For K2-3b we find marginally significant evidence for a Transit Timing Variation between the K2 and Spitzer epochs. A proposal to follow-up planets hosted by M stars byK2usingSpitzerobservations at4.5μm (IRAC Channel 2) was approved in Cycle 11 (Werner, PI; Program11026). The multiple system K2-3 (EPIC 201367065) has three planets orbiting an M0 star(Crossfield et al. 2015) as described in Table 1. The three planets (b,c,d) have radii in therange of 1.2-2.4 R and were observed by K2 with 8,4 and 2 transits, respectively. All observations were obtained with Spitzer IRAC Channel 2 (4.5 microns) using staring mode observations
