Description
We present SEDs for single-age, single-metallicity stellar populations (SSPs) covering the full optical spectral range at resolution (FWHM = 2.3Å). These SEDs can be regarded as our base models, as we combine scaled-solar isochrones with an empirical stellar spectral library (MILES), which follows the chemical evolution pattern of the solar neighbourhood. The models rely as much as possible on empirical ingredients as also employ extensive photometric libraries. Thanks to the unprecedented parameter coverage of the MILES library we synthesize SSP SEDs from intermediate- to very-old age regimes, and the metallicity from super-solar to [M/H] = -2.3, all for a suite of IMF shapes and slopes. We propose a new Line Index System (LIS), based on flux-calibrated spectra, to avoid the intrinsic uncertainties associated with the Lick/IDS system and provide more appropriate, uniform, spectral resolution.

    Measuring the Masses of the TOI-700 Planets with ESPRESSO

    Over the past three decades, astronomers have discovered that small, rocky planets in temperate orbits are common around our neighboring stars. Whether or not these planets can maintain atmospheres is an open question in the field. Recently, considerable attention in this search has been focused on M dwarfs stars, as their small sizes make it

    3.5 years of observing exoplanet day sides with CHEOPS

    Characterising Exoplanets Satellite (CHEOPS) is the first ESA exoplanet space mission. The satellite carries a 30cm telescope, optimised to deliver exquisite (ppm-level) photometry of bright exoplanetary systems at optical wavelengths. CHEOPS has spent approximately 20% of its observing time during its 3.5-year long nominal mission studying

    Finding Water Worlds with Transit Timing Variations

    Models predict that planets with water-rich compositions may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Precise mass and radius measurements for small planets allow us to identify candidate water worlds that have bulk densities too low to be consistent with a rocky composition
