Cytochrome c (Cytc) and cytochrome c oxidase (COX) catalyze the terminal reaction of the
mitochondrial electron transport chain (ETC), the reduction of oxygen to water. This …

Optical atomic clocks, due to their unprecedented stability 1 , 2 – 3 and uncertainty 3 , 4 , 5 –

Doppler measurements from Keck exhibit a sinusoidal periodicity in the velocities of the G0
dwarf HD 209458, having a semiamplitude of 81 ms-1 and a period of 3.5239 days, which is …

We describe the high resolution echelle spectrometer (HIRES) now in operation on the
Keck Telescope. HIRES, which is permanently located at a Nasmyth focus, is a standard in-plane …

We analyze 8 years of precise radial velocity measurements from the Keck Planet Search,
characterizing the detection threshold, selection effects, and completeness of the survey. We …

We present a catalog of nearby exoplanets. It contains the 172 known low-mass companions
with orbits established through radial velocity and transit measurements around stars …
