The spectra of brown dwarfs are key to exploring the chemistry and physics that take place in their atmospheres. Late-T dwarf particularly diagnostic due relatively cloud-free atmospheres deep molecular bands. With use powerful atmospheric retrieval tools applied these objects, direct constraints on molecular/atomic abundances, gravity, vertical thermal profiles can be obtained enabling a broad exploration chemical/physical mechanisms operating We present uniform analysis low-resolution IRTF...
Condensation and sublimation of ices at the surface planet is a key part both Martian H$_2$O CO$_2$ cycles, either from seasonal or diurnal aspect. While most ice located within polar caps, frost known to be formed during nighttime down equatorial latitudes. Here, we use data Emirates Mars Infrared Spectrometer (EMIRS) onboard Mission (EMM) monitor evolution over almost one year. The unique local time coverage provided by instrument allows us observe apparition in second half night around...
Abstract We present the first spatially resolved scattered-light images of four debris disks around members Scorpius-Centaurus (Sco-Cen) OB association with high-contrast imaging and polarimetry using Gemini Planet Imager (GPI). All are for time in polarized light, one disk is also detected total intensity. The three imaged HD 111161, 143675, 145560 symmetric both morphology brightness distribution. systems span a range inclinations radial extents. 98363 shows indications asymmetries...

Spectra of brown dwarfs are key to exploring the chemistry and physics that take place in their atmospheres. Late T dwarf (850 - 500 K) spectra particularly diagnostic due relatively cloud free atmospheres deep molecular bands. With use powerful atmospheric retrieval tools, these properties permit proper allocation constraints on molecular/atomic abundances temperature profiles. These can be used derive elemental (metallicity, C/O), chemical disequilibrium, non-radiative-convective...
