Mass mixing ratios and condensate/cloud of the O2/CO2 atmosphere – model 5. The 15 major gas phase species are shown in the left hand side column and the solid and

Eigenfunctions describing tidal lava flows on a hemispherical dayside magma ocean. The nightside is masked in brown. Left half shows the scalar potential functions ϕr, computed by taking the real

Earth-like and super-Earth candidates from Bryson et al. (2021) are displayed in the effective temperature–instellation flux plane, as in Bryson et al. (2021). The conservative and optimistic habitable zones defined

Schematic of a zebrafish embryo at the late cleavage stage. The blastoderm is positioned at the AP atop the yolk cell at the vegetal pole (VP). The last row of

Spectra of different stellar types. On the left, scaled and vertically shifted flux from NewEra stellar grid is shown on the y-axis and wavelength is shown in microns on the

Spectroscopic observations of β Pic obtained on April 29, 2025. The HARPS spectrum is not flux-calibrated and was simply renormalized to a flux level similar to that of the STIS
