WVir, and RVTau stars) instability strip on the H-R diagram, as well as the brightest part of their period-luminosity relation, with radial pulsation periods longer than 20days (Soszyński et al. 2017). However, it has been shown that RVTauri variables follow a steeper period-luminosity relation compared The NASA Kepler and follow-on K2 mission (2009-2018) left a legacy of data and discoveries, finding thousands of exoplanets, and also obtaining high-precision long time-series data for hundreds of thousands of stars, including many types of pulsating variables.

A new P−L relation has been calibrated for the galactic Cepheids which have a steeper slope than that derived for the Population II Cepheids and RV Tauri stars in Magellanic ... The unqualified term instability strip usually refers to a region of the Hertzsprung–Russell diagram largely occupied by ... Position on the HR diagram. All the observational features can be explained if the star is at its first crossing of the instability strip, i.e. it has not passed yet the first dredge-up, which is expected to destroy completely lithium and modify the CNO abundances, bringing to the surface CN-cycle processed material. ...

As many as 10\\% of OB-type stars have global magnetic fields, which is surprising given their internal structure is radiative near the surface. A direct probe of internal structure is pulsations, and some OB-type stars exhibit pressure modes ($β$ Cep pulsators) or gravity modes (slowly pulsating B-type stars; SPBs); a few rare cases of hybrid $β$ Cep/SPBs occupy a narrow instability strip ...
