ffortissimo is a JAX-based freeform forward-modeling pipeline that fits complex dust distributions and infers scattering properties in KLIP-reduced images of circumstellar disks such as HR 4796A.
High-contrast imaging of 18 compact-object binaries yields no robust tertiary detections and rules out main-sequence tertiaries at projected separations greater than 500 au for Gaia systems and 2000 au for BH LMXBs.
Multi-band optical imaging and modeling of the HR 4796A debris disk show highly forward-scattering dust consistent with large absorptive grains plus a possible clump and exterior halo.
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.
JWST/MIRI imaging of Eps Ind A b prefers a double-PSF model likely due to systematics but demonstrates sensitivity to exomoons down to 1.3 M_Jup at separations >2 AU and 2.5 M_Jup at 0.52 AU.
New companion HIP 53005 C shows strongly conflicting mass estimates of ~80 M_Jup from photometry versus ~185 M_Jup from dynamics, possibly indicating binarity or an unseen closer companion.
