Given the potential of ensemble asteroseismology for understanding fundamental properties of large numbers of stars, it is critical to determine the accuracy of the scaling relations on which these measurements are based. From several powerful validation techniques, all indications so far show that stellar radius estimates from the asteroseismic

We present a compilation of orientations of seven temples dedicated to the Phoenician goddess Astarte across the Mediterranean. The chronology of the earliest temple corresponds to the Early Bronze Age – temple of Baalat Gebal at Byblos, 2800 BCE – but the rest dating back to the Iron Age, from IX to IV BCE. We find that most temples follow a sun

We present a spectral analysis of the spectrum from the Hubble Space Telescope Cosmic Origins Spectrograph (HST/COS) of the southern VY Scl nova-like variable BB Doradus, obtained as part of a Cycle 20 HST/COS survey of accreting white dwarfs (WDs) in cataclysmic variables. BB Dor was observed with COS during an intermediate state with a low mass

Context. Research on supernovae (SNe) over the past decade has confirmed that there is a distinct class of events which are much more luminous (by 2 mag) than canonical core-collapse SNe (CCSNe). These events with visual peak magnitudes ≲-21 are called superluminous SNe (SLSNe). The mechanism that powers the light curves of SLSNe is still not well

I n the first decade of t h e 21 st cent u ry , the Egyptian - Spani sh Mission on Arc h a eoastronomy of ancient Egypt performed a detailed sta tistica l analysis of the orientation patterns of the temple s of Pharaonic Egypt , resulting in most interesting outcomes such as t h e justified proposal of seven families of astronomical orientations

The nature of warm, ionized gas outside of galaxies may illuminate several key galaxy evolutionary processes. A serendipitous observation by the MaNGA survey has revealed a large, asymmetric Hα complex with no optical counterpart that extends ≈8″ (≈6.3 kpc) beyond the effective radius of a dusty, starbursting galaxy. This Hα extension is
