No TiO detected in the hot-Neptune-desert planet LTT-9779 b in reflected light at high spectral resolution

Astronomy & Astrophysics
LTT-9779 b is an inhabitant of the hot-Neptune desert and one of only a few planets with a measured high albedo. Characterising the atmosphere of this world is the key to understanding the processes that dominate in reducing the number of short-period ...

Could the Hercules satellite be a stellar stream in the Milky Way halo?

, 2010
We investigate the possibility that Hercules, a recently discovered Milky Way (MW) satellite, is a stellar stream in the process of formation. This hypothesis is motivated by Hercules' highly elongated shape as well as the measurement of a tentative ...

Warme dichte Materie in Natur und Labor: Ein ungewöhnlicher Materiezustand

Physik in unserer Zeit, Volume 56, Issue 4, Page 198-204, July 2025.
Warme dichte Materie rückt immer mehr in den Fokus, nicht nur in der Physik und Astronomie, sondern auch in den Ingenieurswissenschaften und sogar der Politik. Es handelt sich um interessante, aber auch komplizierte Zustände von Materie, die unser Verständnis ihrer Funktionsweise herausfordern.

RXTE Observations of LMC X-1 and LMC X-3 [PDF]

, 1998
Of all known persistent stellar-mass black hole candidates, only LMC X-1 and LMC X-3 consistently show spectra that are dominated by a soft, thermal component.

Improved radial velocity orbit of the young binary brown dwarf candidate ChaHa8

, 2010
The very young brown dwarf candidate ChaHa8 was recently discovered to have a close (~1AU) companion by means of radial velocity monitoring. We present additional radial velocity data obtained with UVES/VLT between 2007 and 2010, which significantly ...

REGAT: A permanent GPS network in Algeria, configuration and first results

Heliyon, 2019
The REGAT (“REseau Géodésique de l'ATlas”) geodetic network is composed of 53 continuously–recording GPS stations distributed in the Algerian Atlas. It spans the whole width of the Algerian coast and reaches 300 km inland, with inter-sites distance of ...

Zehn Jahre Gaia‐Messungen: Die hochgenaue Kartierung des Himmels

Physik in unserer Zeit, Volume 56, Issue 4, Page 175-183, July 2025.
Das astrometrische Weltraumobservatorium Gaia der Europäischen Weltraumorganisation hat die astrometrische Forschung revolutioniert, indem es unter anderem präzise Positionen, Bewegungen und Entfernungen von fast zwei Milliarden Himmelsobjekten gemessen hat. Damit stellt es wertvolle Daten für fast alle Gebiete der Astrophysik bereit. Nach dem Ende der

Giant Radio Pulses from the Crab Pulsar

, 2004
Individual giant radio pulses (GRPs) from the Crab pulsar last only a few microseconds. However, during that time they rank among the brightest objects in the radio sky reaching peak flux densities of up to 1500 Jy even at high radio frequencies.

Dormant black hole candidates from Gaia DR3 summary diagnostics

Astronomy & Astrophysics
We present a rigorous identification of candidates for dormant black holes (BHs) and neutron stars (NSs) in binaries using summary statistics from Gaia Data Release 3 (DR3), rather than full orbital solutions.
