Outline of Annual Research Achievements |
In the past year, I published one article in AJ, entitled "Three Small Planets Transiting a Hyades Star" (DOI: 10.3847/1538-3881/aaa841), and submitted two others to AJ: "47 validated planets from K2 Campaign 10," and "Spitzer Transit Follow-up of Eight Planets from K2," as well as coauthored other works: "Characterizing K2 Candidate Planetary Systems Orbiting Low-Mass Stars III: A High Mass & Low Envelope Fraction for the Warm Neptune K2-55b" (Dressing et al, submitted), "Mass determination of the 1:3:5 near-resonant planets transiting GJ 9827 (K2-135)" (Prieto-Arranz, submitted), "Planetary Candidates from K2 Campaign 16" (Yu et al., submitted), "275 Candidates and 149 Validated Planets Orbiting Bright Stars in K2 Campaigns 0-10" (Mayo et al, 2018), "An Improved Transit Measurement for a 2.4 R_{Earth} Planet Orbiting A Bright Mid-M Dwarf K2-28" (Chen et al, 2018), "K2-141 b: A 5-M; super-Earth transiting a K7 V star every 6.7 hours" (Barragan et al, 2018), "K2-155: A Bright Metal-Poor M Dwarf with Three Transiting Super-Earths" (Hirano et al, 2018, AJ), "Exoplanets around Low-mass Stars Unveiled by K2" (Hirano et al, 2018), "The discovery and mass measurement of a new ultra-short-period planet: EPIC~228732031b" (Dai et al, 2017), "K2-137 b: an Earth-sized planet in a 4.3-hour orbit around an M-dwarf" (Smith et al, 2017), "Three Small Super-Earths Transiting the nearby star GJ 9827" (Niraula et al, 2017), "K2-66b and K2-106b: Two extremely hot sub-Neptune-size planets with high densities" (Sinukoff et al, 2017).

Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
I am currently working on a fourth paper, entitled "71 Validated Planets from K2 Campaigns 5--8," which I will submit to AAS Journals.

Strategy for Future Research Activity |
I will continue to be involved in two large collaborations in the USA, Europe, and Japan, the aim of which is to discover and characterize new planetary systems found by the NASA K2 mission. The primary focus of my work in these projects has been to perform detailed transit light curve modeling and statistical analyses, which results in the confirmation of new planets and accurate estimates of their fundamental properties, such as size and equilibrium temperature. In addition, I have performed detailed light curve analyses to detect rotational spot modulation using Gaussian Process models, which sometimes results in higher precision estimates of stellar rotation periods. Finally, much of my work is related to ongoing follow-up observations: I have conducted high angular resolution speckle imaging follow-up of hundreds of candidate planet host stars, transit follow-up observations and analyses using ground -based telescopes and the Spitzer space telescope, as well as identified targets for high precision radial velocity follow-up observations with world-class instruments such as HARPS and HARPS-N.
