A systematic analysis of the mixing ratios with respect to H 2 O for eight species (CH 3 OH,
HCN, NH 3, H 2 CO, C 2 H 2, C 2 H 6, CH 4, and CO) measured with high-resolution infrared …

This review covers the work of the three decades since the first spectroscopic identification
of the H 3+ molecular ion outside of the laboratory in 1988, in the auroral atmosphere of the …

We present the design, construction, and performance of SpeX, a medium‐resolution 0.8–
5.5 μm cryogenic spectrograph and imager, now in operation at the 3.0 m NASA Infrared …

PHOTOCHROMIC materials1, 2 change colour on absorption of light, whereas
electrochromic materials3, 4 change colour in response to an electrically induced change in …

We report new magnetic field measurements for 14 classical T Tauri stars (CTTSs). We
combine these data with one previous field determination in order to compare our observed …

We examine several theories that describe how stellar magnetic fields on classical T Tauri
stars (CTTSs) interact with their surrounding accretion disks. We demonstrate that these …

The saturated hydrocarbons ethane (C2H6) and methane (CH4) along with carbon
monoxide (CO) and water (H2O) were detected in comet C/1996 B2 Hyakutake with the use …

We report the results of a high-resolution spectroscopic survey for CO fundamental emission
from T Tauri stars. CO fundamental emission is frequently detected, with the likely origin of …

The∼ 2 Myr old classical T Tauri star CI Tau shows periodic variability in its radial velocity
(RV) variations measured at infrared (IR) and optical wavelengths. We find that these …
