We have surveyed Kepler’s supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 L ⊙ in all stars within 20% of the...
No surviving evolved companions of the progenitor of SN1006
TypeIa supernovae are thought to occur when a white dwarf made of carbon and oxygen accretes sufficient mass to trigger a thermonuclear explosion. The accretion...
No swan song for Sun-as-a-star helioseismology: Performances of the Solar-SONG prototype for individual mode characterisation
The GOLF instrument on board SoHO has been in operation for almost 25 years, but the ageing of the instrument has now strongly affected its performance...
No temperature fluctuations in the giant H II region H 1013
While collisionally excited lines in H ii regions allow one to easily probe the chemical composition of the interstellar medium in galaxies, the possible...
No unique solution to the seismological problem of standing kink magnetohydrodynamic waves
The aim of this paper is to point out that the classic seismological problem using observations and theoretical expressions for the periods and damping times of...
Noble gases and nitrogen in samples of asteroid Ryugu record its volatile sources and recent surface evolution
The near-Earth carbonaceous asteroid (162173) Ryugu is expected to contain volatile chemical species that could provide information on the origin of Earth’s...

Nodal precession of a hot Jupiter transiting the edge of a late A-type star TOI-1518
TOI-1518b, a hot Jupiter around a late A-type star, is one of the few planetary systems that transit the edge of the stellar surface (the impact parameter b ~ 0...
