CRIRES+ spectra of 30 RGB stars in Liller 1 reveal multi-metallicity sub-populations with abundance trends matching the bulge field and Terzan 5, indicating in-situ formation rather than globular-cluster origin.
Retrievals on six isolated brown dwarfs yield near-solar C/O (0.51-0.63), metallicities, and 12C/13C ratios (91-155) supporting molecular cloud fragmentation origin.
Resolves six speculative companions into one giant planet, one eccentric brown dwarf, two low-mass stars, and two stars with no detectable companions.
Injection-recovery tests show PCA can yield higher SNR but more signal degradation than Molecfit or Astroclimes; all methods struggle at low orbital velocities, and a prior H2O claim on τ Bootis b is not recovered.
New spectroscopic measurements of RGB stars in nine open clusters confirm mass-dependent extra-mixing processes and indicate that initial 17O and 18O abundances may vary.

Comparing telluric removal methods in their capability to recover injected exoplanet atmosphere signals with high resolution emission spectroscopy
Injection-recovery tests show PCA can yield higher SNR but more signal degradation than Molecfit or Astroclimes; all methods struggle at low orbital velocities, and a prior H2O claim on τ Bootis b is not recovered.
