The Near-InfraRed Planet Searcher (NIRPS) is a new ultra-stable infrared (YJH) spectrograph that will be installed on ESO's 3.6-metre Telescope in La Silla, Chile. Aiming to achieve a precision of 1 m s-1, NIRPS is designed to find rocky planets orbiting M dwarfs, and will operate together with the High Accuracy Radial velocity Planet Searcher

We present J' and K' imaging linear polarimetric adaptive optics observations of NGC 1068 using MMT-Pol on the 6.5-m MMT. These observations allow us to study the torus from a magnetohydrodynamical (MHD) framework. In a 0.5 arcsec (30 pc) aperture at K', we find that polarization arising from the passage of radiation from the inner edge of the

Dynamical arguments indicate that 944 Hidalgo is most likely an extinct or dormant comet. Hidalgo's Tisserand invariant (T = 2.07) suggests strongly that this object came either from the Kuiper belt or the Oort cloud (e.g., Weissman et al. 2002). We obtained low-resolution near-infrared spectra in the 0.8-2.4 micron region on UT Oct 22, 23, Nov 19

Following the report of a new outburst of the accreting millisecond pulsar SAX J1808.4-3658 by Markwardt and Swank (ATel #1728), the source was observed using the CTIO/SMARTS 1.3m telescope on MJD 54732.0998, in I- and H- bands. We clearly detected the source at magnitudes significantly higher than its quiescent level, confirming that the source is

C60 and C70 fullerenes were neutron-bombarded to an integral dose of 3.28×1016 n cm−2. After the neutron treatment the trichloromethane soluble fraction was determined spectrophotometrically and C60 insoluble fraction was found at 3.8% while the insoluble fraction of C70 17.9%. The formation of the CHCl3 insoluble fraction is due to polymerization

Context. It is still being debated whether the well-known metallicity-giant planet correlation for dwarf stars is also valid for giant stars. For this reason, having precise metallicities is very important. Precise stellar parameters are also crucial to planetary research for several other reasons. Different methods can provide different results
