US-Cuba Normalizations: Strategic Impacts For U.S. National Security

Part of the JGI/LACC/ARC/U.S. Southern Command Policy Roundtable Series, this commissioned paper discusses the strategic impacts regarding the renewed relationship between the U.S. and Cuba. Piccone discusses the implications for U.S.-Cuban bilateral relations, U.S. relations in the region, and U.S. relations on the global level.https://digitalcommons.fiu.edu/jgi_research/1034/thumbnail.jp

U.S.-Cuba Normalization: U.S. Constituencies for Change

The United States and Cuba made important strides after the re-launch of diplomatic relations between the two countries under Presidents Barack Obama and Raul Castro in 2015-2016. These changes were both psychological and symbolic as key themes of mutual respect, sovereignty and reconciliation gained ground. They were also pragmatic, cutting across a wide range of issues from travel and hospitality, which has helped catalyze a major increase in U.S. travelers to the island, to telecommunications and migration. These measures reflected the emergence of an effective coalition of U.S. constituencies that organized individual and joint efforts to regain the advantage over the traditional pro-embargo approach of the Cuban diaspora. With the inauguration of Donald Trump in January 2017, however, forward momentum in bilateral relations has nearly ground to a halt as the hardline Cuban exile community has reasserted primacy in shaping U.S. policy toward the island. Nonetheless, the Republican Party is divided over how far to roll back the changes made by Obama as specific constituencies with the most to gain from normalization defend their interests in continued normalization. The author analyzes the various U.S. stakeholders pushing for relaxation of the embargo and how the Obama administration’s policies benefited them. It will also look at the role of the U.S. Congress and the prospects for rapprochement in the years ahead

A Six Year, Low-resolution, Multibroadband Transit Photometry Study of HD 189733b

Transmission spectroscopy offers an invaluable opportunity to characterize the atmospheres of exoplanets. We present new ground-based optical transmission spectra of the hot Jupiter HD 189733b, derived from nine transits observed over a six year time span (2016–2021) using near-simultaneous $u^{\prime} g^{\prime} r^{\prime} i^{\prime}$ broadband observations. We achieve an average (best) precision of 435 (280) ppm by implementing an optical diffuser on the prime focus spectrograph from the 2.3 m Wyoming Infrared Observatory telescope. The data provide new measurements of the apparent planetary radius with respect to the stellar radius, the spectral index of atmospheric opacity, and the time variability of the two quantities. Our results indicate an enhanced spectral slope in the optical regime ≈2.4 times steeper than would be expected from canonical Rayleigh scattering and that is consistent with earlier measurements of a super-Rayleigh slope (SRS). While the effect of stellar activity on the transmission spectrum complicates the measurement of the spectral slope, our multiepoch data set over six years can measure and average over stellar variations, yielding a mean spectral index of −9.9 ± 4.4. The 1200 K equilibrium temperature of HD 189733b places it in a sweet spot for the formation of SRSs and is consistent with vigorously mixing hazes in the atmosphere. Additionally, we find variations in the depth of the lightcurve during two of the transits, explainable as an increase in occulted star spots during June 2021. Although the star is active, the mean level of stellar activity does not seem to vary dramatically over our six years of observations, leading us to conclude that the variability in stellar activity is modest at most
