ROTATIONAL VELOCITIES FOR M DWARFS
- J. Jenkins, L. Ramsey, +4 authors D. Pinfield
- Physics
- 27 August 2009
We present spectroscopic rotation velocities (v sin i) for 56 M dwarf stars using high-resolution Hobby-Eberly Telescope High Resolution Spectrograph red spectroscopy. In addition, we have also… Expand
The mass of the Pleiades
- D. Pinfield, R. Jameson, S. Hodgkin
- Physics
- 1 October 1998
A membership catalogue for the Pleiades is divided into four mass bins, and a tidally truncated King profile is fitted to each bin with good agreement with the data. The tidal radius of the cluster… Expand
Chromospheric activities and kinematics for solar type dwarfs and subgiants : analysis of the activity distribution and the AVR
- J. Jenkins, F. Murgas, +6 authors D. Pinfield
- Physics
- 3 March 2011
Aims. In this work we present chromospheric activity indices, kinematics, radial-velocities, and rotational velocities for more than 850 FGK-type dwarfs and subgiant stars in the southern hemisphere… Expand
Effective temperatures, rotational velocities, microturbulent velocities and abundances in the atmospheres of the Sun, HD 1835 and HD 10700
- Ya.V.Pavlenko, J. Jenkins, H.R.A.Jones, O. Ivanyuk, D. Pinfield
- Physics
- 24 January 2012
We describe our procedure to determine effective temperatures, rotational velocities, microturbulent velocities, and chemical abundances in the atmospheres of Sun-like stars. We use independent… Expand
Optical and Infrared Spectroscopy of SN 1999ee and SN 1999ex
We report optical and infrared spectroscopic observations of the Type Ia SN 1999ee and the Type Ib/c SN 1999ex, both of which were hosted by the galaxy IC 5179. For SN 1999ee we obtained a continuous… Expand
Metallicities and activities of southern stars
- J. Jenkins, H. Jones, Y. Pavlenko, D. Pinfield, J. Barnes, Y. Lyubchik
- Physics
- 8 April 2008
Aims. We present the results from high-resolution spectroscopic measurements to determine metallicities and activities of bright stars in the southern hemisphere. Methods. We measured the iron… Expand
A very cool brown dwarf in UKIDSS DR1
- S. Warren, D. Mortlock, +21 authors B. Venemans
- Physics
- 5 August 2007
We report the discovery of a very cool brown dwarf, ULAS J003402.77−005206.7 (ULAS J0034−00), identified in the UKIRT Infrared Deep Sky Survey First Data Release. We provide optical, near-infrared,… Expand
