The region around the Herbig Ae/Be star LKH-alpha198 was imaged at 10 micrometer with the CAMIRAS camera at the Canada-France-Hawaii Telescope and the Nordic...
A dehydrated space-weathered skin cloaking the hydrated interior of Ryugu
Without a protective atmosphere, space-exposed surfaces of airless Solar System bodies gradually experience an alteration in composition, structure and optical...

A dense 0.1-solar-mass star in a 51-minute-orbital-period eclipsing binary
Of more than a thousand known cataclysmic variables (CVs), where a white dwarf is accreting from a hydrogen-rich star, only a dozen have orbital periods below...
A DESGW Search for the Electromagnetic Counterpart to the LIGO/Virgo Gravitational-wave Binary Neutron Star Merger Candidate S190510g
We present the results from a search for the electromagnetic counterpart of the LIGO/Virgo event S190510g using the Dark Energy Camera (DECam). S190510g is a...
A detailed analysis of the Gl 486 planetary system
Context. The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3...
A detailed analysis of the properties of radiolyzed proteinaceous amino acids
The thermal behaviour of 21 proteinaceous l-amino acids either as pristine samples and also as radiolyzed (3.2 MGy) samples was studied with the differential...
A Detailed look at Chemical Abundances in Magellanic Cloud Planetary Nebulae. I. The Small Magellanic Cloud
We present an analysis of elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe) and focus initially on 14 PNe in the Small...
A detailed look at the stellar populations in green valley galaxies
The green valley (GV) represents an important transitional state from actively star-forming galaxies to passively evolving systems. Its traditional definition...
