SUMMARY:The Neutron Star Circus: Accretion Flows and Thermonuclear Bursts 
DESCRIPTION:The Neutron Star Circus: Accretion Flows and Thermonuclear Burs
 ts \nDr. Manuel Linares\n\nNeutron stars in low-mass X-ray binaries (NS-LM
 XBs) are unique laboratories of accretion physics, strong gravity and ultr
 a-dense matter. I will give an overview of what we have learned in recent 
 years by studying accretion flows and thermonuclear bursts in these system
 s.\nI will first present and discuss the main result of a systematic study
  of their different accretion states: the discovery of a correlation betwe
 en luminosity and spectral hardness. I will also show ongoing work on the 
 connection between active (1-100% of the Eddington luminosity) and quiesce
 nt (down to 10^-6 times Eddington) phases of NS-LMXBs.\nIn the second part
  I will focus on the relation between mass accretion rate and the recurren
 ce time of thermonuclear bursts (explosive nuclear burning on the neutron 
 star surface), presenting results at the lowest and highest mass accretion
  rates. In particular, I will argue that rotation plays a larger role than
  we thought in setting the nuclear burning regimes on an accreting neutron
  star.
