There may be a difference in how its sub-parts (it's actually an array of CCDs) are positioned (for instance, for spectroscopy in principle you don't need a large field of view, but can do with a long array rather than a more square one), but the design of the individual CCDs are the same. I'm not really into the instruments of Gaia, but I assume that differences in the CCDs are due to different wavelength regions being probed. However, whether the CCD is used for imaging (photometry and astrometry) or spectroscopy does not have anything to do with the CCD it's just a matter of inserting a grism or not. And further out in the IR, CCDs aren't even used, instead using something which are just called "detectors". But for instance, the Nordic Optical Telescope has a CCD which is optimized for blue wavelengths, but has quite a lot fringing in the near-infrared. In astronomy, we tend to be short of light, so here we almost always want them to be as sensitive as possible (an exception may be observations of the Sun, which I don't know much about).

With an estimated equilibrium temperature of ∼2600 K, TOI-2260 b is also the fourth hottest known planet with Rp<2R⊕. TOI-2260 is a young (321☙6 Myr) G dwarf that is among the most metal-rich ( = 0.22☐.06 dex) stars to host an ultra-short-period planet. TOI-1860 is the youngest (133☒6 Myr) solar twin with a known planet to date. We use ground-based observations collected through the TESS Follow-up Observing Program (TFOP) and two vetting tools - DAVE and TRICERATOPS - to assess the reliabilities of these candidates as planets.

These planet candidates cover a broad range of planet radii (Rp∼0.6−2.0R⊕) and orbit stars of various magnitudes (Ks=5.78−10.78, V=8.4−15.69) and effective temperatures (Teff∼3000−6000 K). We identify 18 potentially terrestrial planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS) that would make ideal targets for these observations. The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. As nouns the difference between astrometry and astronomy is that astrometry is (astronomy) the branch of astronomy that deals with the measurement of the positions and motions of celestial bodies, particularly starstars while astronomy is the study of the physical universe beyond the earth's atmosphere, including the process of mapping locations. The dashed lines indicate the minimum values a target should have to be observed with JWST. Astrometry is a related term of astronomy. Bottom: emission spectroscopy metric versus apparent Ks magnitude for each planet candidate and planet. The ecliptic plane and ecliptic poles (i.e., the JWST continuous viewing zones) are shown as dashed black lines. Top: coordinates of the TESS planet candidates in this paper (white circles), validated TESS planets in this paper (black circles), validated TESS planets (blue squares), confirmed TESS planets (blue diamonds), and confirmed pre-TESS planets (red hexagons).
