The EXtreme PREcision Spectrograph (EXPRES) is an optical fiber fed echelle instrument being designed and built at the Yale Exoplanet Laboratory to be installed on the 4.3-meter Discovery Channel Telescope operated by Lowell Observatory. The primary science driver for EXPRES is to detect Earth-like worlds around Sun-like stars. With this in mind, we are designing the spectrograph to have an instrumental precision of 15 cm/s so that the on-sky measurement precision (that includes modeling for RV noise from the star) can reach to better than 30 cm/s. This goal places challenging requirements on every aspect of the instrument development, including optomechanical design, environmental control, image stabilization, wavelength calibration, and data analysis. In this paper we describe our error budget, and instrument optomechanical design.

  1. Measuring the Suns radial velocity variability due to supergranulation over a magnetic cycle

    astro-ph.SR 2025-06 conditional novelty 7.0 of 10

    Using eight years of HARPS-N Sun-as-a-star radial velocities, the authors measure a clear variation in the supergranulation timescale over the solar cycle, strongly anti-correlated with the sunspot number.

  2. The Fe I 4377 {\AA} Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis

    astro-ph.SR 2026-07 conditional novelty 6.0 of 10

    Spectral ratio analysis of the Fe I 4377 Å line in HARPS-N Sun-as-a-star spectra recovers facular filling factors that track SDO/HMI measurements (Pearson R = 0.587–0.927).

  3. TOI-7154b: A Close-in Massive Brown Dwarf in an Eccentric Orbit

    astro-ph.EP 2026-05 unverdicted novelty 4.0 of 10

    TOI-7154b is a 71.7 M_J brown dwarf in an 8.86-day eccentric orbit around a G star, with eccentricity and age suggesting stellar-like fragmentation origins.
