A Large Ground-based Observing Campaign of the Disintegrating Planet K2-22b
© 2018. The American Astronomical Society. All rights reserved. We present 45 ground-based photometric observations of the K2-22 system collected between 2016 December and 2017 May, which we use to investigate the evolution of the transit of the disintegrating planet K2-22b. Last observed in early 2...

All rights reserved. We present 45 ground-based photometric observations of the K2-22 system collected between 2016 December and 2017 May, which we use to investigate the evolution of the transit of the disintegrating planet K2-22b. Last observed in early 2015, in these new observations we recover the transit at multiple epochs and measure a typical depth of <1.5%. We find that the distribution of our measured transit depths is comparable to the range of depths measured in observations from 2014 and 2015. These new observations also support ongoing variability in the K2-22b transit shape and time, although the overall shallowness of the transit makes a detailed analysis of these transit parameters difficult. We find no strong evidence of wavelength-dependent transit depths for epochs where we have simultaneous coverage at multiple wavelengths, although our stacked Las Cumbres Observatory data collected over days-to-months timescales are suggestive of a deeper transit at blue wavelengths. We encourage continued high-precision photometric and spectroscopic monitoring of this system in order to further constrain the evolution timescale and to aid comparative studies with the other few known disintegrating planets. 2018-11-29T07:40:25Z 2018-11-29T07:40:25Z 2018-11-01 Journal 00046256 2-s2.0-85056709669 10.3847/1538-3881/aae31b https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85056709669&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/62686 |
