Receipt: # 15969-25 The atmospheres of Neptune-size (2-6 Earth radii) planets are poorly understood mainly due to the degeneracy between composition and high-altitude aerosols. Past studies have tried to resolve this degeneracy and understand the aerosol formation processes using statistical methods. A recently found potential correlation between equilibrium temperature and water absorption amplitude indicates a possible decrease aerosol formation as planets become hotter. However, due to the very limited sample size (~6) with only 2 warm (>850K) planets so far showing any water spectral features, this possible correlation is extremely statistically fragile. We propose to observe HD 219666b, a hot-Neptune recently discovered by TESS. Its high equilibrium temperature (~1073K) and ideal radius (4.71 Earth radii) make it a prime target to test our current understanding of the relationship between temperature and aerosol formation. While a prominent water spectra features will confirm that hotter planets have clear atmospheres and improve the target selections for future JWST observations, a featureless flat spectrum can also provide new observational insights into aerosols formations. We plan to observe HD 219666b using HST/WFC3 for a total of 6 visits with 3 in G102 and 3 in G141 grism to obtain a high S/N transmission spectrum. With additional wavelength coverage from G102, we will be able to precisely constrain the metallicity and the cloudtop pressure without degeneracy. In addition, G102 allows for detecting possible helium escape from the upper atmosphere by searching for excess emission from the 10830 angstrom helium triplet lines. We will observe 6 transits of HD 219666b with G141 and G102 grism. Guangwei Fu is a graduate student working with Prof. Drake Deming.
