The targets are faint in the FUV and the anticipated S/N is low enough that fixed-pattern noise mitigation is not helpful. However, reducing the splits from 4 to 2 increases the effective exposure time by more than 25%, which is more beneficial to the program. The Rossby Conundrum (This is the HST part of a joint Chandra/HST program: the Chandra proposal abstract follows). Key goal of cool-star astrophysics: link high-energy XUV surface emission to the dynamo that generates magnetic flux deep inside a star. In the 1980s, the Rossby number (Ro) -- ratio of rotation period to a convective timescale -- unified Ca II chromospheric fluxes over a broad span of main sequence spectral types. Encouraging, because Ro plays a central role in terrestrial and stellar dynamo theories. A recent attempt to achieve a similar unification at high energies was faced with a quandary: large dispersion and missing data in the K types. New joint Chandra/HST observations of K dwarfs in the young Hyades cluster could help resolve the conundrum. Testing the Ro framework is a crucial step toward unraveling the enigmatic dynamo. The "Rossby Conundrum" refers to a recent study, by Ayres & Buzasi (2022), that derived empirical convective turn-over time scales for a carefully-selected sample of stars with known rotation periods and existing FUV and X-ray observations. (The Rossby number, Ro, is a ratio of the rotation period to the turn-over time, and plays a key role in magnetic dynamo theories not only for stars, but also terrestrial planets with liquid interiors.) The FUV and X-ray measurements were combined into a hybrid "XUV" flux that was intended to represent the radiative cooling of the corona, and thus is a proxy of the heating by magnetic reconnection in surface active regions. The Ro ratio was known to tighten up correlations of chromospheric CaII emission, which displayed a spectral-type-dependent spread when compared to rotation periods alone. The hope was that the XUV flux would display a tight relationship with Ro, demonstrating a deeper connection between Ro and the dynamo. In practice, the correlation was expressed in terms of empirical turn-over times, which were compared with existing stellar-structure modeling. While there was good agreement with the theory for the Sunlike G2-G8 stars, there was a larger dispersion in the later, K-types, as well as a few gaps in the temperature coverage. (There also was another conspicuous missing-data gap among the warmer F-type stars, which is the subject of a companion HST/Chandra investigation.) The Rossby "Conundrum" is whether the dispersion seen among the existing sample of K dwarfs is a result of limited statistics or instead might be signaling the existence of a hidden parameter governing the association between the stellar Rossby number and the dynamo. To address the Rossby conundrum among the cooler objects, one needs a collection of single dwarf stars (given the more advanced state of dynamo modeling on the main sequence, especially the Sun), which have similar fundamental properties, such as age and chemical composition, differing mainly in surface temperature. The latter controls the convective properties and thus the turnover time. The targets should have well-determined rotation periods, ideally via photometry (avoiding the inclination ambiguity of spectroscopic velocities); and be accessible in the X-rays and FUV, to derive the crucial XUV metric. Such homogenous stellar samples can be found in nearby young Galactic clusters. The 650 Myr Hyades, in particular, is close enough (47 pc) to have K dwarfs that can be captured by Chandra at high energies, and by HST in the FUV. (The more distant Pleiades cluster is a less-favorable option because its K dwarfs are 8x fainter.) Further, Kepler K2 yielded uniformly and accurately measured photometric rotational periods for many of the fainter Hyades K dwarfs; while Gaia DR3 provides reliable distances, colors, broad-band magnitudes, and radial velocities. After carefully vetting candidates from a recent catalog, just ten fell in the key Teff range needed to fill existing gaps in the turn-over time diagram, and bolster statistics where the dispersion is large. The proposed targets have PROT= 9-13 d, and appear to be single by virtue of H-R diagram position and infrared K-band speckle imaging. Cosmic Origins Spectrograph is the best choice for FUV spectroscopy of faint objects like the Hyades K dwarfs. COS can achieve full-coverage FUV spectra (i.e., C III 117 nm to He II 164 nm) by combining two medium-resolution settings, G130M-1222 and G160M-1533 (low-res grating COS G140L misses important Si III 120 nm and N V 123+124 nm). The G130M-1222 detector gap excludes H I 121 nm Ly-alpha, so there are no safety concerns. This simple combination is optimum for the relatively faint Hyades K dwarfs. The two COS CENWAVEs can be accommodated in a single orbit per star. The NUV imaging target acquisition is suitable for the Hyades V-magnitude range. Time-Tag is the default exposure mode, and is helpful to identify any transient flare events (although expected to be uncommon for Hyades activity levels). The NUV imaging target acquisition can be done for the brighter targets with Mirror-A and the BOA; the intermediate brightness, cooler targets can be done with Mirror-B and the PSA; and the faintest, latest target can utilize Mirror-A and the PSA. In one orbit, accounting for overheads, about 1 ks of exposure is available for each CENWAVE (2 ks total in the 2 nm overlap between them). These targets are faint in the FUV, so it is beneficial to deploy only 2 of the default 4 FP-POS splits for each setting. FP-POS 1+2 are used with M-1222 to fully capture Si III 120 nm; FP-POS 3+4 are used with M-1533 to fully record the Fe II 134 nm + Fe XXI 135 nm region. Restricting the FP-POSs yields 25% more exposure time: the S/N will not be high enough to make best use of the fixed-pattern mitigation delivered by the full complement of FP-POS splits in any case. The M-1533 exposures can be done at Lifetime Position 4 (instead of LP6 with its high-overhead lamp-flash calibrations) because the duration of each visit is a single orbit. PI Ayres has extensive experience with HST, especially the UV spectrographs, dating back to the launch of Hubble. He has carried out many HST programs, mostly concerning high-energy stellar phenomena, and has published numerous papers on HST data.
