The abundance of Li in stars formed within the past 5 Gyr is logN(Li)=3.2(+/-0.2), while the corresponding value for the oldest stars in the Galaxy is logN(Li)...
Progenitor and close-in circumstellar medium of type II supernova 2020fqv from high-cadence photometry and ultra-rapid UV spectroscopy
We present observations of SN 2020fqv, a Virgo-cluster type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting...
Progress Report on the Large-Scale Polarization Explorer
The large-scale polarization explorer (LSPE) is a cosmology program for the measurement of large-scale curl-like features (B-modes) in the polarization of the...
Projection effects in the spectra of early-type pulsating stars
The relation between the surface velocity of a pulsating star in the star's inertial frame and the apparent expansion velocity measured by a remote observer has...
Prolate rotation and metallicity gradient in the transforming dwarf galaxy Phoenix
Transition type dwarf galaxies are thought to be systems undergoing the process of transformation from a star-forming into a passively evolving dwarf, which...
A prevalent but untested paradigm is often used to describe the prominence-cavity system: the cavity is under-dense because it is evacuated by supplying mass to...
Prominences are intriguing, but poorly understood, magnetic structures of the solar corona. The dynamics of solar prominences has been the subject of a large...

Prominence Thread Seismology Using the P 1/2P 2 Ratio
Prominence threads are expected to be cold plasma condensations in a long magnetic tube. Because of this density inhomogeneity along the magnetic field, the...
