	abstract = {We analysed the complete set of bursts from the neutron star low-mass 
X-ray binary 4U 1820-30 detected with the Rossi X-ray Timing Explorer
(RXTE). We found that all are photospheric radius expansion bursts, and
have similar duration, peak flux and fluence. From the analysis of
time-resolved spectra during the cooling phase of the bursts, we found
that the relation between the bolometric flux and the temperature is
very different from the canonical F ∝ T4 relation which
is expected if the apparent emitting area on the surface of the neutron
star remains constant. The flux-temperature relation can be fitted using
a broken power law, with indices ν1 = 2.0 ± 0.3 and
ν2 = 5.72 ± 0.06. The departure from the F ∝
T4 relation during the cooling phase of the X-ray bursts in
4U 1820-30 could be due to changes in the emitting area of the neutron
star while the atmosphere cools down, variations in the
colour-correction factor due to chemical evolution, or the presence of a
source of heat, e.g. residual hydrogen nuclear burning, playing an
important role when the burst emission ceases.},
