- Fig2_9:
Evolution of the Sun in an H–R diagram, from core H-burning to the white dwarf stage. The
life of any star begins with core H-fusion (sphere 1), while occupying a characteristic location
on the diagram: the main sequence. In a star like the Sun, H will be depleted near the center
after 10 Gyr. Following recontraction, H will ignite in the shells that surround the He-rich
core, leading to a dramatic increase in size, approximately reaching the orbit of the
Earth. Its path along the H–R diagram will subsequently follow the subgiant and red giant
branches, while the Sun becomes a giant star (2). The temperature rise at the center during
recontraction will eventually lead to core He-ignition. Its evolution will continue through the
horizontal branch (3). After 1 Gyr, helium will be depleted at the center and double H- and
He-shell burning will set in. The Sun, by then a bright star (4), will climb the asymptotic
giant branch (AGB). The late stages will be characterized by a gentle ejection of the outer
layers at v = 50 - 100 km s-1, giving rise to a planetary nebula, while the inner, CO-rich 0.6
Msun of the Sun will smoothly evolve into a stable, white dwarf configuration.

Positron emission tomography (PET). The most commonly used compound in PET scanning is
fludeoxyglucose (FDG), an analogue of glucose that contains 18F. Concentrations of
this radiotracer imaged in the body provide an indicator of tissue metabolic activity. This is,
for instance, used to unveil cancer metastasis. When the short-lived radiotracer decays, it
releases a positron that annihilates with a close-by electron producing a pair of γ-rays.
In short, a PET scan (left panel) detects
the high-energy radiation indirectly produced by a positron-emitting radiotracer. Shown in
the right panel is a maximum intensity projection of a positron emission tomography corresponding
to a female after intravenous injection of 18F encapsulated in FDG, 1 hour before
measurement. Aside from the expected accumulation of the radiotracer in the heart, bladder,
kidneys, and brain, liver metastases of a colorectal tumor are also visible. Credit:

and v > 8000 km s-1 (3). (Bottom) Dispersion in distance moduli after substraction of the

- Fig5_13:
Expansion rates in three possible models of the universe. Measurements at low redshifts (low
recession velocities) are in agreement with Hubble’s law, V = Ho D. If the expansion rate
has always been the same, all objects will follow a linear fit in a Hubble diagram, regardless
of their redshift (central line). In a universe now slowing its expansion rate (and therefore
characterized by a faster expansion in the past), an object at given distance D would show a
velocity larger than Ho D. Conversely, in a universe now speeding up, an object at distance D would show a velocity smaller than Ho D.

Snapshots of the merging episode of two white dwarfs of masses
1.2 Msun and 0.4 Msun, simulated

secondary star hit the surface of the primary (top right panel), the shocked regions reach
T = 5 × 108 K. The colliding particles are reflected almost instantaneously by the hard
boundary of the primary. As mass transfer proceeds (central panels) the accreted matter
is shocked and heated on top of the surface of the primary. This matter is actually ejected
and a hot toroidal structure forms (right middle panel). Temperatures exceed 109 K, and
nuclear reactions transform the accreted He into C and O. Figure from Guerrero,

SEM image (panel a) and NanoSIMS isotopic maps of 26Al/27Al, 48Ti, and 44Ca/40Ca
(panels b, c, and d) of an unusually large (about 30 μm) SiC grain of type X named Bonanza. The SEM image suggests that the grain is actually an aggregate of smaller grains. The anomalous
size of Bonanza has allowed the determination of isotopic ratios for many different elements,
including Li, B, C, N, Al-Mg, Si, S, Ca, Ti, Fe, and Ni. Isotopic analyses yield
12C/13C = 190,
14N/15N = 28,
δ29Si/28Si = -282‰, and
δ30Si/28Si = -442‰. Mg is
completely dominated by the presence of radiogenic 26Mg, from the decay of 26Al (the ratio 26Al/27Al inferred in the grain lays in the range 0.4 – 0.9). The region with the largest 44Ca/40Ca ratio (0.05), corresponds to a titanium subgrain, which exhibits as well the largest concentration of 48Ti. This suggests that the 44Ca excess corresponds to in situ decay of 44Ti. The Ti, Fe, and Ni isotopic patterns are typical of other X grains and can be reproduced by mixing different layers in models of core-collapse supernovae. Figure adapted from Zinner et al.

Evolution of the density and magnetic field during the merging of a binary neutron star
system, at four different times (t = 7.4 ms, 13.8 ms, 15.3 ms, and 26.5 ms). The simulation yields a rapidly spinning black hole surrounded by a hot and highly magnetized torus. Magnetohydrodynamical instabilities can actually amplify an initially turbulent magnetic field along the black hole spin axis, naturally resulting in a relativistic jet, potentially powering a short GRB.
