The Post-AGB Star IRAS 07253–2001: Pulsations, Long-Term Brightness Variability and Spectral Peculiarities
AbstractThe observations and comprehensive study of intermediate initial mass stars at the late stages of evolution, and after the asymptotic giant...

Stars That Breathe
Stars which show a variation in their brightness are called variable stars. Pulsating variables are intrinsic variable stars whose brightness changes...

X-ray Emission of Massive Stars and Their Winds
Most types of massive stars display X-ray emission that is strongly affected by the properties of their stellar winds. Single nonmagnetic OB stars...

Isolated Neutron Stars
Non-accreting neutron stars display diverse characteristics, leading us to classify them into several groups. This chapter is an observational driven...

Timing Neutron Stars: Pulsations, Oscillations and Explosions
Neutron stars, whether isolated or in a binary system, display a varied and complex phenomenology, often accompanied by extreme variability of many...

Transiting Exoplanet Survey Satellite (TESS) Observations of Flares and Quasi-Periodic Pulsations from Low-Mass Stars and Potential Impact on Exoplanets
We have performed a search for flares and quasi-periodic pulsations (QPPs) from low-mass M-dwarf stars using Transient Exoplanet Survey Satellite ...

Signatures of convection in the atmospheres of cool evolved stars
Evolved cool stars of various masses are major cosmic engines, delivering substantial mechanical and radiative feedback to the interstellar medium...

Making waves in massive star asteroseismology
Massive stars play a major role not only in stellar evolution but also galactic evolution theory. This is because of their dynamical interaction with...

Circumbinary Planets Around Evolved Stars
The current state of evidence for planets around evolved star binaries is reviewed. The small sizes of compact evolved stars leads to sharp features...

Radio pulsations from a neutron star within the gamma-ray binary LS I +61° 303
LS I +61° 303 is one of the rare gamma-ray binaries
1 that emit most of their luminosity in photons with energies beyond 100 MeV (ref.2 ). It is well...

Accreting Strongly Magnetized Neutron Stars: X-ray Pulsars
X-ray pulsars (XRPs) are accreting strongly magnetized neutron stars (NSs) in binary systems with, as a rule, massive optical companions. Very reach...
